Bests & Worsts Reviews from Amazon

Buyer beware! Worked great, but does not last. My first one worked for a little over a year and then suddenly stopped, the second did the same thing just after one month. $170 down the drain, since the return window of 30 days just ended. Update: sportDOG contacted me the next day and they helped me getting it working again over the phone. So glad, because when it works it does a great job. I will test it for a couple of weeks and then upgrade my review if it keeps working.
