The polar RS300X works well. But footpod the è little a cumbersome one confronted to some other I& #039; the seen VE (especially Nike+ one). The monitor has many functions, but during l' è training in some way difficult to read especially, poichè the numbers are thin and little ones, the step. During the night it really becomes hard to use.

You can’t go wrong with this monitor. It’s great to keep close track of your stats and performance. . .

I purchased this watch after running my first marathon and having a conversation with a guy during the race, who was wearing a polar watch. It really came in handy during the race to make sure we were on pace for our goal. Using a standard watch is nice but as we all know, race mile markers aren’t certified and therefore your splits will be off. The footpod is great but you absolutely need to calibrate it. Not sure if its my stride but it was not very accurate out of the box, I ran a half marathon (13. 1 miles) and it registered about 14. 5 miles. The menus are fairly easy to figure out but I did need to consult the user manual a few times. I personally love the fact that you can customize and switch between 5 different views on the fly while running. The heart rate monitor is your basic type and works well. Overall, I would say this product is worth it if you do longer races including or above a 10k or if you train by yourself. Having the information this watch provides is great for pushing yourself.

I have given to this product 4 stars only perché no other the avévano still examined and the didn& #039; the t it wants to put the kabosh on it when it is concluded me on the restitution.
I have bought this product with the making models competition from Garmin, Timex and Suunto. I have intentional to control & #039; em all outside and I have found for/against to everyone. At the end, they have gone with the Garmin and much happy one I have made. It tries my review là (releases over my name in order to see mine other reviews).
Polar è un' company of physical form and the training excel in the generation all little ones and of many senses to defy themselves and to measure your progress, or on the vigilance in itself that accompanying the software/Web site.
The vigilance in itself was the pià ¹ small of the four that I have examined, than good è for me from I& #039; m. a gallon and not necessarily to try a clunker. But, polar not è un' company of the vigilance and extension in their design of outlandish person. I wish that it has observed hardly a little pià ¹ watch-as and less like the sure foreign implantations that they have cad they give from a vase of Vulcan.
Nevertheless, I could go with the polar one, but what has killed l' transaction for me was l' unità of GPS. I have decided that I really have need of the GPS for l' pursuit where I& #039; the VE be and how far I& #039; the gone VE. There are two problems with Polar& #039; solution of s GPS:
- the implantations: Polar& #039; s the GPS è un' unità separated tied to your arm that contains three batteries of the AAA that works from spremuta after 8-12 hours. It& #039; pig of the battery of the S.A. That GPS è un' unità of thirds party that are use of the Timex that polar, così they& #039; with reference to the same ones. The hatch of this small what of GPS of the plastic era so as to close hard – me and an other critic has had a similar problem with l' unità Timex-stamped – nearly nixed it for that problem alone. Così, blow or lack on the fabrication. The è problem that unloading and recharging the batteries every little operations will obtain of being a controversy. And, seemed the normal foolish operation già ¹ the road with that thing on your arm. L' unità of it contains it to Garmin all to right all' inside of the vigilance in itself. Advanced Così.
- the software: If you& #039; king interested in downlaoding (uploading) your training in your PC and nell' to analyze to your miles totals, the calories and really to see your route covered on a program, richiederà many points for you and a small PC of good sense to make it with the Timex and the polar solutions. The didn& #039; look of t even to Suunto& #039; s, perché their solution of GPS had exited from mine wraps of price. Garmin& #039; the software of s easy è così – my review reads and you& #039; the ll it sees.
But, if you are really in your series and rep and objectives and objectives, or già well with other polar products, this is probably that one of right for you.

Nice, light, with good features but i dont understood why it’s not compatible with polar software. Big cons for me. . .
