Zovii Alarm Disc Lock - ZD6

Bought one of these as they were on offer and I didn't already have a disc lock as I just used chains. Was pretty impressed with the alarm for the price, it is very loud. Easy to install the battery & easy to put on and take off the bike.
However, I forgot my disc lock was on the bike, rolled it backwards to get off my drive, the disc lock snapped when it made contact with another part of the bike. This didn't fill me with confidence in this product at all. If that's all it takes to get it off, I may as well not even put one on when I park my bike somewhere that I can't use a chain. Could have just been a bad batch from production, but not what you'd want or expect.

Good quality not used in wet weather yet.

Very easy to set up and use sturdy item and looks nice. Peace of mind for protecting bike and at a good price.

This alarm is very loud when I set it off. It has a 5 second timer before it starts screaming. It has quite a weight to it but it fits well on my 125 with only 1cm wide holes in my disc. So far hasn’t set off falsely or anything like that. The tiny screw to put back in thought after putting the battery in we spent about an hour trying to get back in. Quite w difficult design to make sure everything is in line but at least the battery lasts a long time.
