Xena Disc Lock with Alarm XX10

Comment: The sensor works so good it scares me. When you unlock it you have to get it off the bike quick or it starts screaming. It is very sensitive to movement. I seems impossible that it could be removed without the key due to the sensitivity and attention it attracts when it goes off. it would I would recommend this to everyone with a bike.

Comment: I bought this because I moved to an apartment complex and the bike now sits outside of a garage. I got it in and it was heavy, and I do mean heavy. My friend owns one of the $20 locks from here and though it's nice, this thing is much better. It's sensitive enough that if I make the mistake of locking my bike before putting my cover on, the act of putting the cover on will set off the alarm. It's not so sensitive that it goes off all hours of the night. On windy days, it won't go off when the cover billows. It did however scare the nieghbor kids when they started to bump into my bike. I was on the other side of the complex (130 ish units) and still heard it. I wish that it had a little red bungie to remind me that it's there, but the alarm does that well enough that I won't be making that mistake again. So if you're worried about your bike being stolen and want to know if someone is messing with your bike, get this and suprise them with 120db if ear piercing, attention grabbing and all in all rude awakening. Also Jafrum IS the cheapest for this item and I did plenty of shopping around. I honestly don't know why I bother, Jafrum is just that good.

Comment: So far the locks doing its job I still have the bike. I love the alarm nice and loud also helps me from making a big mistake when I forget its on the disk
