I originally ordered the GPS keyring tracker which I found to be compact, simple to use and the set-up was easy by following the set-up video. However, my husband has Alzheimer’s, and in my circumstances the 60 seconds update was the most suitable but it meant that the tracker had to be charged up every night. I was advised by Aaron at Techsilver that the Waterproof GPS tracker might be more suitable as it has a longer battery life. I returned the original tracker and ordered the Waterproof Tracker. This tracker is equally easy to use and set up. It is slightly bigger but still not cumbersome and the battery life is much better – worth the extra cost. Throughout all of this I found the customer service to be excellent – quick responses to emails and very patient.
