  • H1 Heart Rate Sensor


H1 Heart Rate Sensor is rated 3.25 out of 5 by 8.
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.

Rated 1 out of 5 by from Works with no training apps? I have had this for a few year and was hoping I could pair it with something, but apparently there is nothing mobile it pairs with other than the watch it came with (poor display I feel, very hard to see, but maybe there is a setting I'm missing?)

Rated 1 out of 5 by from Don't waste your money I purchased one a month ago and the transmitter from the strap stopped working. Unfortunately I ordered a second one about two weeks ago and it worked once and the transmitter stopped working after one use. The battery does not stay in contact inside the transmitter, very poor engineering. I wasted a lot of money
