Title: Great for a few months, but...
Review: This was $30 in Jan '09. I bought it to track my HR during the P90X program. It worked great for a few months giving me the basic features I needed; time, avg HR and Peak HR. I took a few months off of P90X and used it only a few times over the next few months. I recently started the P90X program again and a couple weeks into the program with daily use, the transmitter just stopped working. I replaced the battery, but still nothing. Fortunately I bought a 1 year warranty, so I was able to get a full refund. I will not buy this product or brand again. I hope this helps.
