  • H1 Heart Rate Sensor


H1 Heart Rate Sensor is rated 3.4 out of 5 by 10.
Rated 5 out of 5 by from Used for high intensity spinning class The stationary bikes we ride have a heart rate display that I can read. I am over 70 and want to keep my cardio exercise in a range. The chest monitor gives me confidence that the reading is accurate.

Rated 3 out of 5 by from Good, but will it last? I got this to replace an earlier model that finally exhausted its non-replaceable battery after years of use. I like that I can replace the battery in the H1, but the chest strap is lighter than the old model, with a flimsy hook/loop fastener that is harder to use and less durable than the old one. I am not a large person (size L shirt) but the strap barely fits around my chest at its longest adjustment.

Rated 4 out of 5 by from Heart Strap Stopped Working The rating is this high because when the product is working it is great. I have used my FT4 watch and H1 strap/sensor for almost 3 years on a daily basis. The strap/sensor stopped working and I tried everything to get it to work. Figured the battery was finally dead as this was the first time I receive the "check transmitter" sign on the watch. Changing the battery and washing the strap throughly did not work. This is a great product except when it breaks for no reason and will not work again even after the batteries in both pieces are changed. The watch works fine and I have replaced that battery a few times in almost 3 years. The strap/sensor stopped out of the blue and putting a new battery in did not work.

Rated 2 out of 5 by from Poor Seal Design The seal around the battery is extremely poor and requires replacement. But find a replacement is impossible. Once the seal o-ring is distorted, moisture enters the battery cover. Then it becomes a matter of compromising the battery/electronics with body sweat. You can only find the o-ring as part of a battery replacement assembly for about $10US.

Rated 4 out of 5 by from This is the second time I am having to replace the transmitter in the past few years. I wear it almost daily and it has overall served me well. I don't understand why the transmitter fails so often. I have followed all instructions about detaching it from the strap for storing and washing my strap frequently. I have yet to find a monitor I like better.

Rated 5 out of 5 by from Got what I ask for The belt came within 3 days of ordering. It was an updated version of the one I wore out. It does exactly what it is suppose to do. I am very pleased with the product.

Rated 4 out of 5 by from This has always worked just fine for me. My trainer suggested this with the FT7 and it worked great for a year until the watch battery died. I haven't gotten around to replacing it, but I'm sure this strap still works fine.

Rated 5 out of 5 by from Replaceable battery! A great improvement over the previous model that required shipping back to the manufacturer to replace the battery.
