I have the Yale Smart Living Home Security System, that I purchased in the UK and brought the System over to Spain, where I now live. I wanted to have a spare Door/Window Contact. It took nearly 3 months to be delivered to my address in Spain, as the goods were detained in Customs, until additional paperwork was supplied. Pleased to have had it finally delivered. It is a good home security system.

second purchase of these additions for my alarm system, easy to install and set up, no problems as long as you get the 2 components as close as possible without them damaging each other.

Easy to change like for like

Works just as it should and comes with lots of mounting options. Perfect

Cheap and cheerful

Work well and are easy to link to the alarm controller but rather obtrusive on a window frame. It would be nice if they came in brown as well.
