Magnetic Quadband GSM Independent Security Alarm Alertor

Pros: works ok

Cons: It hasn´t any cons

Other: It´s fantastic!!"!!!!!!!
AH don´t remember cancell code pin for the sim because if you don´t this the unit never works (It´s logic, but you can´t find this instruction at the instruction manual)

Pros: Does what it should do, the unit itself has good build quality exept for the power switch - operates fine but looks and feels very unreliable.
The unit sends SMS in case of intrusion and calls after sendidg SMS for audio surveilance. This option is not in the manual and is a little extra for the money. Another good thing not in the manual - you can call the unit and start listening immediately.

Cons: The power adaptor has ONLY flat US design - I wonder why DX ignores this. It's still 110-240 VAC so it's only a question of an appropriate mains adaptor.
Besides that the chager did not work out of the box. Had to take it apart to find a loose (!) capacitor inside. It was plugged in the PCB, both legs had bad soldering and it did not have any contact. After I soldered it it still worked for 15 minutes and went to flames. Be careful and don't leave unattanded for the first 30 mins of operation!!!

Other: It's definately worth it's money. I'll consider buying one or two more for that price.

Pros: Works fine, once you understand the manual. Very compact. Location function is pretty accurate.

Cons: The manual is written in very poor English, making it really hard to understand. The manual does not state how you should set the phone number that the device uses to call or to send alerts to. Any clues ?

Other: Fine, considering the low price. But please, improve the manual !

Pros: It has good autonomy, it's a small device and easy to conceal. Also it can be used for bigger DIY project because of the way it was made.

Cons: Instruction manual on some points needs a bit improvement mainly English translation, because some things you simply must test out to be sure you understood it well.

Other: Great device, use it for your shed with valuable tools or vacation house.
