## Customer Reviews

### ⭐⭐⭐⭐ A very good system. Little effort in installing
*by T***E on 6 October 2014*

A very good system. Little effort in installing. The manual is ok.• internal siren is on short leads which have to be extended in order to meet suitable location point.• There's no manufacture's details to contact regarding after sales matters.• This unit do not have the option of using land line telephone, should anyone is hoping for such a connection.

### ⭐⭐⭐⭐⭐ Very good product for the money (maybe not for people without some technical background)
*by F***. on 8 July 2015*

Very good product and easy to install. It works very well. The manual is poor at some points. I think it's a good product but you have to have some technical background or previous experience on setting alarms or configuring systems using numeric commands. Also please have a look on the answered questions specially regarding to external siren pairing, it's a bit tricky and the manual isn't clear enough.

### ⭐ Malfunctioning Unit
*by F***. on 24 June 2017*

The GSM works only for few seconds after powering up the unit.
