Bests & Worsts Reviews from Amazon

I am leaving this feedback as I was previously very pleased with my Leaf. I started having issues with it several months ago - it was losing data often. The company replied to my concerns and gave me directions to reset it, which I did - I had to also replace the perfectly good recently replaced battery though. Well now it will not sync at all, hasn't synced in about a month. I tried replacing the battery and going through the steps they recommended. The company is now ignoring my customer service requests and not responding now that my Leaf is completely useless and won't do anything. I've asked for a replacement and they will not respond to me. Oh well, it was nice for the 6 months that it worked but I am so disappointed in the outcome and customer service.
