GSM Realtime Anti-Theft Vehicle Tracker

Pros: It just works as expected.
you can call to hear what's going on in the device, and you receive a call when sound noise level is high, as well as text message on vibration event.
battery last for a couple of days in full charge.
haven't tried SJ command yet, and WO command location is not supposed to work in Ukraine.

Cons: 12v power supply intended to use with 12v automobile power gets hot when connected.

Other: good enough

Pros: Small good battery easy to hide behind radio in the car and uses very little amperage. RADIO is a great power source for ignition on 12V.

Cons: NO ENGLISH MANUAL!!!

Other: Without an english manual I cant test it. without being able to use it I wont buy and sell these in my electronics store

Pros: Well, it works.

Cons: No way to find information about the brand, or model in English. You must know Chinese to be able to do anything with this thing.

Other: Learn Chinese or find someone who knows if you want to use this. The thing works as expected but you cant even start it or do anythong wothout understanding chinese. Othewise it's a very good way to keep strack of your car or bike.

Pros: Size, portability, battery and charger, built in mic. Works well once you can get pass the Chinese manual. Plug in your SIM card and you're all ready to go.

Cons: Tracking is network dependent. Mine came with scratches on it but works fine. Not for the fussy.

Other: A good buy it if you have use for the features other than tracking, at least for me. No regrets here.
