Rated 3 out of 5 by Good device, terrible strap This was my first polar product that I received as a gift. I use the watch maybe once a week; what I would consider a light to moderate use for a device like this. While the actual device/computer is functional, the strap really brought down my review of this watch. It becomes very brittle over time and breaks. Not very impressed considering this was (at the time) a pretty expensive purchase. 09/25/2015
Rated 1 out of 5 by Quality issue w/ strap I am an avid Polar fan and long term user; Polar has accompanied me on marathon training. RX300 was my third Polar. It does the job technically, but the strap has been made with the wrong material and just breaks down too fast. Becomes brittle over time and I really tried to hang on to it as long as I could (see picture), but it it time for a new one. 09/23/2015
Rated 1 out of 5 by RS300X loses HRM signal I've had the RS300X for a year or so and while it can generally detect the HRM initially, it loses the HRM signal every few minutes. I've tried every corrective action suggested by the manufacturer but none of them have resolved this problem. The HRM functionality is the reason I bought this watch, and without that functionality, this watch is useless to me. 09/01/2015
Rated 4 out of 5 by Great Monitor, Not so good strap. I've used and abused this model for about 3 years. About a year in I noticed some cracking in the band. Another two years later it finally broke. I have owned several Polar monitors in the past and never had this problem. I also used the receiver as my everyday watch, and wore it nearly 24/7 (even in the shower). Overall this is a good training tool, with some great features and I feel is a great value in the Polar product line up. I'd be more upset about the band breaking if Polar wasn't so good with repair and customer service. I can't complain with that at all. As a matter of fact I'm replacing my old RS300X with a new RS300X thanks to Polar's trade in program. I plan to use it ONLY for training and not as my everyday time piece. Maybe it'll last a little longer that way. 06/18/2014
