This is my fourth HRM and by far the best. The display is big and very readable even in dim light without using the indiglo. My last two HRMs were the older model Timex Ironman 100 lappers. They became very unreliable even with new batteries. I used to have to use electrode gel just to get them to work at all. This HRM gives me an accurate reading immediately and continues to do so as my heart rate changes during my workout. It works great even without electrode gel. It doesn't have any fancy features but I don't need them. It does record your time in the zone that you can set and you average and peak heart rates. It also has a recovery time feature that measures how many BPM your HR drops in one minute. The sensor belt will also work with the HR display most treadmills and other indoor machines. This HRM has already improved my training significantly because it is so accurate and responsive. I highly recommend it. 5 stars

With so many heart monitors available, I had some difficulty deciding on what to buy. I decided on the Timex T5G971 because I have always wore the Timex Iron Man. I have come to know Timex as a dependable and affordable sport time piece, and so far I am very happy with the heart monitor. It was easy to set up and works great! I have also read that other brands require that you send off to the company for replacement batteries, but such is not the case with the Timex. 5 stars

The product is very easy to use once you read the directions. It syncs up easily with the watch monitor. One extra bonus that I did not anticipate is that it syncs with the cardio machines that I use at the gym, so I don't even need to look at the watch to see my heart rate. I have also enjoyed seeing the duration of my workout and how many calories I burned. 5 stars

Timex T5G971 Unisex Sports Personal Heart Rate Monitor WatchI bought this heart rate monitor for both my husband and myself. We wanted one that we didn't have to send back to the manufacture or dealer everytime it needed a battery in the chest strap such as the Polar.

We've only been using them for about a month, but so far we really like them. It is very easy to learn hoew to set it and use all of the features. It also is very easy to get started. I put it on and just put a little water on the senors. In the past some of the HRM's I have owned I actually had to start sweating before they would engage.

The only thing on the negative side is that you can not see the time when you are in the Heart Rate Mode. That mode is all you can see. It bothers my husband, but not me.

I'd rate it a 5 instead of a 4, but we really haven't used them long enough to see if changing the battery goes smoothly. The 1st one we bought the buttons were jamed and my husband did change the battery to see if that was the problem. The battery was easy to change in the chest strap, but we had to send it back. The exchange went easily with Amazon. 4 stars

I was looking for a heartrate monitor to track not only my aerobics workouts but also my weight training workouts. I wanted a wireless monitor with a large enough display so it was easy to read (yes, I've joined the reading glasses population). I needed to be able to replace the batteries myself, and it would be nice if it could tell time in case I wanted to use it as a watch.

The Timex met all my needs and at a very good price. I was a bit concerned because I have a 54" chest and a fairly large wrist. I was also concerned because the packaging is not specific about whether it has a coded signal so that it does not pick up other heartrate monitor signals. The chest strap fits me well but if my chest gets too much larger, it's going to be a bit snug. The wrist band also fits but it's in the last hole, and so far, I haven't picked up anyone else's monitor or bled over onto anyone else's cardio machines.

I'm very satisfied with this purchase. 5 stars
