Polar RS800sd Heart Rate Monitor Watch Review

I've been a Polar HR monitor owner since the mid 90's starting with 710i, then 625x, followed by the 725x, and now the RS800SD. I consider myself a serious competitive runner and have been so for over 30 years. Polar introduced me to heart rate monitoring as key component to performance improvement with the book "Training, Lactate, Pulse rate" by Janssen, which is no longer offered by them and may not be published anymore. I have had my VO2, HR curve, and lactate threshold measured in a lab several times over the past few years. I have used this product now for almost a full year and my review will focus on what does all this functionality do to help me improve my running vs some of the other reviews here which seem enamored with purported functionality without connecting the dots for useful training feedback.

The bottom line: This is their flagship product, top of the line and top dollar but Polar seems to have chosen marketing (a shiny sexy small form factor watch with apparently lots of new functions) over solid engineering, useful software functionality, and product reliability. If you already own a 625x or 725x model there is little reason to upgrade as this is an "unfinished product"

The good:

1. Small form factor for watch and footpod
2. Improvement in ergonomics --- buttons and watch face are easier to use
3. More memory --- you can record longer than earlier models at the 1 second rate
4. Running stride length has been added.

The bad:

1. The footpod and HR strap via blue tooth does not seem any more accurate than previous non-blue tooth models and maybe less so regarding footpod functions. HR measurement seems as accurate as earlier models.
2. Software (Polar Pro Trainer 5) has new functions which are questionable at best and misleading at worst -- namely the running "index" function which on a scale of 30 to 76 purports to give you the sum of all calculations with a number which roughly correlates with expected future performance (running times) on various races such as a 5K through a marathon.
3. Customer Service. I was told at first that the inability to record temperature on the watch was a bug in the software. Later was told that the watch could not record temperature (correct). Also was given an excuse as to why temperature was no longer recorded by the watch (users body temperature --- hah! --- it worked well enough on earlier models). And regarding the index calculation, I was never given the algorithm which could at least help me understand what type of math it was doing (it is a mystery to me and the algorithm seems biased to reward you with a higher index score for a lower heart rate and slow time vs a slightly higher heart rate and faster time). Instead I was given a platitude;

"It is worth to remember that in addition to good Running Index, maximal running performance demands good preparation, optimal running conditions, speed endurance and guts. Training quantity and quality have an affect as well as natural talent. The RunningIndex gives a value measured in current circumstances."

I especially like the "guts" comment --- really happy about that as I don't know how I've gotten by over the past 30 years beating people without "guts"

The ugly:

1. Incomprehensible design decision to modify the altimeter sensor holes from recessed (previous polar models) to flush on the bottom of the watch resulting in erroneous readings as soon as you start to sweat (yes you read that right -- sweat) and thus rendering the altimeter function of the watch largely useless unless the watch is worn in such a way (flopping on wrist or strapped to clothing) to preclude the sensor holes from clogging with sweat from your wrist.
2. Software. Looks real nice until you try to modify data. Say you got erroneous distance reading on your last run and you want to easily fix it. You won't be able to. No simple function to correct the total distance of a run and have that correction evenly applied to entire run. This undermines the whole point of exercise comparison within the software. If you go out on two identical runs but the distance recorded by the watch varies by a few tenths of a mile there will be no easy way to correct the data.
3. Temperature. Previous models recorded temperature as a data point whenever you took a lap marker or finished the run. This model does neither requiring you to manually enter the temperature into the software.
4. The running index calculation does not take into consideration temperature (AMAZING! since the book noted at the beginning of this review showed clearly that there is a positive correlation between high temperatures and higher heart rates --- you work harder to cool youself). The lack of temperature calculation (an identical run can have HR vary by 10 BPM based upon temperature) seriously undermines the usefulness of the running index function.
5. No way to tell software about different running conditions for a given distance and have that taken into consideration on the index calculation. Five miles run on a track are treated the same as five miles run on sandy roads or trails. So when you go into the comparison graphs which purportedly allow you to see at a glance trends in your running, you cannot account for different conditions on runs. Neither different temperatures or different running surfaces are considered on calculations. This seriously undermines the usefulness of comparing weeks worth of training runs in order to come up with a performance trajectory and let you know are you ready for that next race.

Until this product I rarely even considered any other HR monitoring tool. Polar may not have made "pretty" watches, but they worked. They made tools for athletes interested in maximizing their performance. The marketing department has apparently taken over the company from the engineers. The company may have "jumped the shark" with this watch and software. I hope I'm wrong and Polar surprises with its next watch. It needs to actually delivers useful functions for serious athletes and not take away functions offered from previous models (temperature and an altimeter which works reliably). And if they are going to go to the trouble of providing a number which tells all --- the index number --- then they better explain how that number is calculated and provide the user with the ability to modify the formula (temperature and surface conditions to start with) in order to meet variable conditions if their engineers and exercise physiologist have not already thought of everything.

And keep the marketing department out of product design until functions are firmly set and don't represent a two steps forward, two steps back design as we see with this model.

I'm always trying to give environmentally-safe products a chance and sometimes they disappoint me. Not this time - I love this product! It smells wonderful - like true lavender essential oil and not the overpowering, chemically-based lavender scent of some of the newer, more mainstream products. The detergent is environmentally friendly, and it's safe for my septic system. I especially love using this detergent on my sheets so that I have a nice lavender haven to lull me to sleep each night. What more could I ask for? I'm sold on this product.

Shoprider Sprinter Four Wheel Personal Travel Scooter Review

Let me begin by saying that I did NOT want to succomb to a scooter. I am relatively young and it was a very difficult hurdle to go over for me. The first time I had to take my scooter out in public was filled dread and worry - for about the first 5 minutes.

We had weighed out several possible choices for scooters and decided on the Shoprider Sprinter for its power and positive reviews on other sites - we bought it through Amazon for the lower price and reliable delivery as well as the fact that Amazon doesn't charge until your item is shipping (we'd been burned for a large amount by another company that pulled the money and after finding that they hadn't shipped the scooter we'd ordered from them we learned that they didn't even have it in stock - despite telling us they did when we ordered! That was a 5 week process of trying to get a refund and we were not going to go through it again!). It arrived in time for an event that we were looking very forward to - a large local Renaissance Festival - and we were thrilled that it got here.

Our local Renaissance Festival is held outdoors on very rough terrain - rocks, roots, hills, dirt, etc. - and I had a great deal of concern about whether any scooter would handle what it would be put through there. I needn't have worried at all! This scooter takes it all on with ease and minor adjustments to the speed when going uphill. The adjustable tiller makes it easy on my shoulders and hands and resting my feet on the front "fenders" makes the ride comfortable for my hips as well. I was wondering how I would manage large radius turns but they have been no problem outdoors even with large groups of people around. Within 5 minutes I was well acclimated to the scooter and caught a few people laughing as I'd cruise around quickly, easily navigating through the areas of the Festival.

We've taken the scooter out twice now and the battery life has been phenomenal! At least 7 hours of driving nearly the entire time and I've only used approximately 2 bars on the battery each time. We give it a full charge before taking it out and it's set. I've also seen others complain about the speed of other scooters but this one is more than enough speed for what I am using it for. I couldn't give you exact mph but I have got great control with the speeds that I have used and have never turned the speed up to more than half of what is offered. When considering the fact that, in previous visits to the Festival, I might last 3 hours and 3/4 of that time would be spent looking for places to sit or sitting, this has been an incredible improvement!

The pneumatic tires were a bit of a concern initially as the terrain would be rough and we worried about flat tires but decided that no-flat tires might be too rough of a ride. We did purchase a fix-a-flat spray if needed but thus far have had no need for it at all and the more gentle ride is definitely an advantage.

The only con I can think of at this time is the fact that it doesn't break down for transport which means we did have to purchase a carrier in addition to the cost of the scooter. It has been quite an investment but considering what it has given back in terms of restoring some mobility and stamina as well as sparing me of the long difficult recovery periods after an outing that I'd been dealing with prior to getting the scooter that had rendered me house-bound - it's been well worth it.

I noticed that Amazon is now offering this scooter for $200 less than we paid for it and for that price I would advise you to jump on it immediately! We bought it about a month ago and have loved the advantages it has offered as far as comfort and time I can spend out doing the things I love to do.

I wouldn't normally leave such a long review but because there are no others and this scooter really does meet any and all of our expectations I had to say something about it. We are very pleased with its performance and my husband now refuses to let me go out without it. It truly has changed my life for the better!
