Buy Sportline Solo 960 Heart Rate Monitor Watch

I bought a Sportline heart rate monitor for my husband and it didn't work the first time I received it through Amazon. I called Sportline customer service and their rep was snippy and told me that I should replace the battery. I replaced the battery for $15 [unbelievable because the watch itself was $85 at the time!]. It worked for four weeks and then the heart rate monitor stopped working again. My husband replaced the battery himself and it still didn't work. I called customer service and they told me that if we replaced the battery ourselves we had voided their warranty. What is that about?!? You can't even replace your own battery? I didn't want to spend $15 every four weeks to replace the battery.I'm very disappointed that I can't return it anymore. This product should work for more than 4 weeks. The customer should be able to replace the battery themselves to save money. It's a very expensive gadget and should work better than it does. I recommend that you buy another product.Get more detail about Sportline Solo 960 Heart Rate Monitor Watch.
