Very happy with product and service.
Good price. Unobtrusive as there is no coloured writing visible to attract attention. Easy to install.

Impossible to activate
Very disappointing - these detectors are German made and I can’t find batteries to fit. Waste of money!

No battery or connection
Alarm arrived with no battery or wire attachment which I can only assume is a mistake, although I’ve noticed similar reviews. The alarm shows that its made in Clare, Ireland, however there are only German instructions. Please send a working alarm.

Delivered with no battery - twice
Despite the technical specification stating that a battery is included it was sent with no battery. I requested a replacement and this too was sent with no battery!

Very dissatisfied
These are sold with a 10 year life, but the 2 I bought both had well less than that. One had a life until 2029, the other 2030.No response from Amazon or supplier.
