Review on Vivitar Activity Action Tracker Gray by Adam Browning

I purchased this from Vons in La Jolla, California for $5.26. Yes, $5.26 with a Vons card. No typo. I just got it out of curiosity and just to compare to my current pedometer. Conclusions: It is necessary to measure stride length to display the total distance traveled in km or miles. The battery cannot be charged or replaced. No backlight. Activity data is not automatically uploaded to the mobile app over a Bluetooth connection. You must enter data manually. As for benchmarking, just forget it. This product is not listed on the manufacturer's website. No wonder the product is thrown away. I don't expect warranty service on a $5.26 gadget.
