Product works as described. I’ve been using for over a year and the magnet holds up very well. The weather proof box does exactly as advertised. It works very well to prevent any and all forms of weather from entering. Signal strength is not affected.

This battery box is absolutely essential for Tracki owners who don't hardwire their device directly to their car's electrical system. I'm amazed at how much extra battery life this gives me! Now I can leave my Tracki in my car for several days at a time without recharge. And the magnet is ridiculously strong! I bought my Tracki and this battery case because there has been a huge upswing in carjackings in my neighborhood. Having extended battery life means my Tracki is almost always safely hidden in my vehicle. If my car gets stolen, chances are good I'll get it back.

Wonderful products. Both Tracki and waterproof box and battery are great. Lots of options in mobile application. I would recommend these products to anyone.

I love this extended battery and case, it lasts sometimes 2 or 3 weeks. I use Tracki for many reasons, child security, car security, and even my safety. When I had car in the shop I could see if they still had on lot or if it was inside being worked on, when they test drive it etc. I highly recommend this product!!!
