Summary: Very difficult directions!
Comment: This product comes with 2 instruction booklets! This should give you a clue about how hard it is to use. I gave this to my daughter as a gift and came very close to returning it Christmas morning. She finally got it working after she soaked the sending device in water while it was strapped across her chest. This seems like a lot of trouble to me but she decided to try it a bit longer before sending it back.
Customer Rating: Summary: This has saved my life!
Comment: I have exercised off and on for years, but then had to stop for awhile after surgery. Starting back, I got this, and always wear it to the gym. It not only lets me know when I'm about to over do it, but I can see if there is any arrhythmia, a sign I am already overdoing. It has taken a little practice for me to learn what is the right amount of exercise for my body, but it has been very helpful! It's great not to have to stop working to take one's pulse.
It isn't possible for my husband to use, however, as he has had rickets, and the chest monitor won't pick up the impulses. I wish there were a wrist-only band to check the pulse.
Customer Rating: Summary: Buy a Pulsar
Comment: Hard to use strap and then monitor was wildly inaccurate. Had two previous Timex's that lasted about 6 months each or less. Returned to Amazon for refund. Upgraded to a Pulsar for $99.00 and it works great. No use spending less on something that doesn't work!
Customer Rating: Summary: Heart Rate Monitor
Comment: I love this monitor. It is a little slow to start, be sure to wet the strap first. Once you start your warm up it gets going. My favorite fitness tool! I won't exercise without it. It's a great purchase for the price.
Customer Rating: Summary: Timex Heart Rate Monitor
Comment: This is the best heart rate monitor I have ever owned. It has features that the more expensive monitors don't offer for the price. You can replace the batteries on both the Timex wrist watch and the chest band, something you can't do on the more expensive brands (on the expensive brands, when the battery dies on the chest strap, you throw it out and purchase a complete new set)
Better yet, the Timex chest band works with the wrist watch of the expense brands (I'm not sure why you would want this because the Timex wrist watch has more features).
From now on, I'll buy only Timex Heart Rate Monitors!
