Bests & Worsts Reviews from Amazon

I had to debate between 4 and 5 stars. I would give this 4-1/2 if I could. Pros: 1) Because of the RHYTHM's ANT+ and Bluetooth capabilities, it pairs with pretty much everything, which is rare in HRM receivers. I have tried it with my Garmin 920XT device, as well as with the Moov and MapMyFitness apps, and ZAP! It's paired. Done! Easy. 2) It provides a dependable heart rate number. Maybe that's a "well, DUH", but if you've used Garmin products (or a few others that routinely get dicey), you know what it's like to wonder if you need to replace your HRM or get to a cardiologist. 3) It's comfortable to wear--I don't even notice it when I'm working out. If you're female and tired of a chest band fighting with your sports bra, this is a blessed relief. 4) It recharges (rather than having a battery that requires tiny screwdrivers and a great deal of patience to periodically replace), and does so easily and efficiently. It comes with a charging cradle. 5) It has a button so you can turn it off and on. Some might consider this an irritation that doesn't belong in the "pro" column, but I like knowing when it's on (it has an LED that flashes--good for knowing it's ready to pair) and being able to preserve the charge if I want to. CONS: 1) This is my bad, so really shouldn't be counted against the RHYTHM, but I'll mention it anyway: It looks ilke a watch. I want it to give me a read-out like a watch on its face. When my Garmin was out for repair and I was pairing this with apps on my iPhone, it kind of drove me nuts. (But still grateful to have a dependable HR read-out even though I had to look at my phone.) So reminder to self, this picks up the HR just like a chest band. It's not a watch. And its so much better than a chest band in so many ways. I apologize--it's probably some unreasonable demand from my reptilian ganglion. 2) The band is a little clunky and does become a sweat magnet as other reviewers have mentioned. I don't mind it, but not a plus--and I haven't run with it in summer heat, at which point I will probably start minding it more. 3) Wild price fluctuations. When I purchased this less than two weeks ago, it was $59.95. As of this writing it's $79.95. I love capitalism as much as the next person, but price gouging, not so much.
