“Another one of those "fiddly to connect" devices but once connected, it seems to work OK.
The siren isn't the loudest but if you mount it slightly off the wall, as per instructions, it would draw attention.
There are auxiliary outputs for an additional siren if you wanted to fit something larger/louder.”
“I read some reviews before buying it and one said it had a very feeble siren. Other reviews were good. The sren sound is very feeble and I hope this was due to a low battery level. If not I'll be asking for a refund.”
“I bought one and after checking with the manufacturer, returned it as the 2nd generation's sirent sounds like a microwave, when it has finished cooking, only slightly louder”
