Review on Mio Slice Heart Rate Monitor - Navy - Small by Matt Spencer

I am a 68 year old male who wanted to make sure he was getting enough exercise. PAI sounded great, get 100 PAI points and you're training hard enough. What a dream. The heart rate monitor sometimes reported a much faster hour than it actually was. The sleep monitor was rarely able to correctly determine the sleep time. The worst part was that I was able to get over 100 PAI in a few days with just moderate training. Support was quick (3 days) but never believed the problem was with the device. They offered to come back, but after being disappointed in both Slice and their Fuse (the issue with the band), I decided to move on. I'm sorry, I hope they find out. PS I didn't buy it from Revain, I bought it when it first came out and was only available from Brookstone.
