  • Great value, with core features available / customizable.
Excellent low cost GPS tracking. Hard to beat this value and convenience, especially if you already have your own SIM The one thing I would personally recommend -- no fault to this product at all -- is that OBD trackers are really easy for potential thieves to notice. BUT there are OBD splitters (T-shaped) that allow you to make it LOOK like your OBD port is unused at first glance, but in reality you have a separate OBD extension cable leading back behind the fuses / otherwise hidden for the GPS tracker. Note that this model won't support all of SinoTrack's app features, but core things like customizable tracking intervals and vibration sensors DO work. It's also surprisingly accurate. Sometimes it is right on the dot -- and when GPS drift DOES occur, it is always well centered so you can very easily pinpoint your car in the middle of the variance reliably. Do note the SinoTrack app isn't a very clean working environment. It's cluttered, unclear, and doesn't specify which features do or don't work for your tracker until you try them. But what I LOVE is that they have DEMO units that you can sample in the app, before you even install your tracker. I STRONGLY recommend downloading the app first to sample one of their public demo units, to see if you can be comfortable with the app interface. Power wise, it can be very low drain if you set it to 30s+ tracking intervals (default is 20s -- I strongly recommend adjusting this if you don't have much overhead on your car battery). For reference, I have this installed on a 2nd car with an incredibly cheap, absolute bottom of the barrel battery with barely any overhead. After 4 days of parking, the voltage readout still remained over 12V (meaning battery still had enough to crank / start the car) ... show more

  • Do not buy - Returning - Defective and or poor Instructions
There is no communication whatsoever with between the device and the desktop or mobile apps. The instructions are not clear. I moved the sim card from ST 901 to the OBD type and suddenly the mobile app gives a repetitious message the immediately appears when you hit the Close X. Tech support takes days to respond due to holidays, vacations and time differences. Update: I returned the defective St 902 obd and replaced with another st902.. I plugged it in a work vehicle. The tracking lags terribly. The historical path is inaccurate. The distance is in Kilometers and not miles. We are in USA we use Miles. I contacted support and they simply said it cannot be changed to Miles. Today the app is blank and isn't connecting to their server. The app has ads. If my network is bad the ads wouldn't show. Some location maps show a China location. I reached out to support to ask why I am seeing a China map instead of a map related to where my vehicle is and that respond was not made. This tracker is not for any serious business at all especially if you plan to have a reliable and consistent tracker and usage data. Sending this back. Support responds after days. ... show more

  • Best affordable Tracker
This is very good. For the fact that there is no monthly payment makes it very attractive.

  • I thought it didn’t need a sim card
The title is a little deceiving. It reads like you don’t need the SIM card but you do need one. This cannot work with T-Mobile. .
