I have been using my new Polar FT4 heart rate monitor literally non-stop for the past four days. I had several goals in mind with this purchase: 1) track my actual daily calorie expenditure (with and without working out); 2) track the intensity of my workouts and measure total calories burned for the workout; 3) use it to plan my meal/calorie distribution throughout the day. Recognizing that my demands on this simple device are ambitious, I can say that overall I am very pleased with it's performance in each area.
Design of the watch:
The watch itself is a "pinkish/neutral/bronze" color that is hard to describe exactly. The good news is that somehow it manages to match basically any color attire you might wear. The band is made out of a disappointingly cheap plastic material that feels like "kid's watch" and pinches your skin easily. Also a nuisance is the fact that the face of the watch has a sort of "fixed hinge" with the sides of the band. In other words, the watch will not lie flat, it's always shaped in a rounded formation. This may be seriously problematic for individuals with very small or very large width wrists. The face of the watch is also a rubbery plastic which seems moderately scratch resistant, though I anticipate that it may get beat up in the weight room at the gym. The display on the face is large and easy to read at a glance, which is nice.
Overall, I would rate the design of the watchband only 2 out of 5 stars. The material is very cheap and causes my skin to itch and sweat where it is strapped on.
Design of the chest strap:
I'm a rather petite female who is relatively lean (< 10% body fat) so the chest strap is conspicuous when I wear it with my sports bra and fitted tank top at the gym. You can see the imprint of the transmitter in the center of my chest, although it doesn't look overly out of place given the fact that I am at the gym. However, I have also been wearing the chest strap with my normal attire outside of the gym and it becomes rather uncomfortable with prolonged use (5+ hours). The strap material is elastic and polyester and easily collects sweat and moisture, so it will need to be cleaned frequently. The front part of the strap (housing the conductive electrodes) is made of a "pleather" type material that is mostly inelastic. If you work out very frequently and for prolonged periods of time, you might consider purchasing the Polar sports bra with built-in chest strap. This particular chest strap appears as though it were designed for a man and is a little cumbersome in my personal opinion. Overall, I would rate the design of the chest strap 2 out of 5 stars.
Features of watch:
The features of the watch/monitor are what make this such an awesome training tool. The watch has three basic features: view your heart rate, view your calories burned, and view your heart rate relative to your "target range." The heart rate reading is constant, real-time and easily read in large print digits. You can also see a reading of your calories burned as you progress through your workout. I chose to track an entire day, wake to sleep--so I tracked 15+ hours at a time in order to view my calories for the day. You cannot collect multiple workouts at one time. For example: you cannot track the day and then simultaneously track your workout on a separate file. You must press "Stop" and start over with a whole new file if you want your actual workout to be separate from your entire day. Also, there is no way to run a stopwatch, which was somewhat disappointing. However, you can view a timer for your workout on one screen that also displays the time of day. Overall, I would rate the features of the watch 4 out of 5 stars. It has great functionality, but could use a few tweaks to make it much more optimal.
Ease of use:
The watch is generally easy to set up and use. It may take a little bit of time to familiarize yourself with the buttons. I also found the backlight button to be mildly irritating. Unlike other watches, if you press the "backlight" button you permanently activate the backlight to come on any time you press any button on the watch. To de-activate it, you need to press and hold the backlight button and wait for a beep. These instructions are not in the manual. I also found that the chest sensor strap was susceptible to giving out when it became especially wet. At one point I had to rinse it with tap water and let it thoroughly dry for a few hours before attempting to use it again. Overall, I would rate the total product with 4 out of 5 stars for ease of use.
Overall Product: I have definitely been showing off my new heart rate monitor to my gym friends and co-workers, and I highly recommend it. Though it has a few shortcomings (mostly in the design of the physical watch) its an outstanding tool and invaluable for individuals who are getting serious about their diet and/or training regimen. I hardly feel justified giving it 3 stars, given that I have been happily using it non-stop for days. But, its shortcomings cannot be overlooked entirely: Overall 4/5 stars. A solid product!
6 Months Post-Purchase Update: I have now been using the Polar FT4 daily for about 6 months. Overall, I continue to be pleased with its features and functionality but I have already considered replacing or "upgrading" into something that addresses a few design flaws which have begun to bug me more and more each workout. First, the watch band is just flat out uncomfortable. There's no other way to describe it. It pinches your skin, refuses to lay flat and generally bruises my wrist when I wear it doing certain weight exercises (like squats and lat pull downs). I actually take it off completely and put it on the bench or in my pocket during some exercises. Second, the fact that you have to scroll through 3-4 screens mid-workout to see your workout timer, heart rate, and calories burned is a bit annoying. It would be nice to be able to see your heart rate on EVERY screen (perhaps in small print along the top of the screen) at a bare minimum. Instead, I fumble between the three screens every few minutes while doing cardio especially. This has gotten a bit aggravating. In terms of the performance of the heart rate sensor, I have begun to notice that if I don't moisten the chest strap prior to putting it on, the watch will completely fail to register a signal until I either start sweating really heavy or wet the strap with tap water. Lately, I have also noticed that the watch "loses its connection" with the chest strap when my arms are fully extended above my head (such as during pull ups) and then when my heart rate reading comes back its either half or double it's actual value. Hmmmm.... I'm not sure what to make of these quirks. Perhaps I need to replace the strap, the batteries or both. Keep in mind I do use these devices at LEAST once per day, and usually twice per day. I would imagine that the amount of wear and tear I put on my heart rate monitor is a bit more than the average user, but not withstanding, I am starting to consider looking in to a different set up.
