Powerful Gas Operated Alarms
AVAILABLE VERY QUICKLY
Found Crime Prevention on a google search.
They had exactly what l was looking for and at a cheeper postage price than Amazon, result.
They also posted to the Republic of Ireland.
I also had to ring the company with a query (l thought l had made an error with the order) and found them to be both extremely friendly and helpful. Plus the delivery was very quick.
I would have no problem recommending them.
