Review on TKSTAR GPS Tracker with Powerful Magnet | Car GPS Tracker for Remote Monitoring - 90 Days Long Standby | Online Real-time Tracking | Vehicle Tracking & Monitoring System - USA by Paul Andrews

Overall great product for the price. I bought it, inserted a SIM card and activated it. At this point the instructions were a bit difficult to understand as I didn't understand that you were texting commands to the sim's phone number to the device and it wasn't explained very well. When I realized it was a no-brainer. The app works very well as does the web version where you can get the history of where the tracker has been. The battery life is phenomenal! It's been over 3 weeks and still has 20% left. Now, this is a vehicle that is used every day, but it is not a delivery vehicle. That's a big part of why the battery lasts so long, going to sleep after a few minutes when the car isn't moving. The magnet was a pleasant surprise as I expected it to fall off and yet it holds. The only thing that is slightly buggy is the geofence. Here you can set alarms when the vehicle enters and leaves the specified area. I'd say it works about 80% of the time, which is good but not great. Again, overall this is a great device and worth the money and if I could I would give this item 4.75 stars instead of four but it's not perfect and shouldn't get a five.
