Stainless Steel 70dB Alarm Security Lock with 3-Key (2 x AAA)

Pros: Great padlock, it's works perfect. easy to use, and it's better, than i thought. it's hard, and when the security alarm is on, it's working suddenly, when somebody is touch it. i like it! the 100db is more powerful, than i though.
what can i say more? it's my best deal at this week. you have to try it. i bought it for my bike, tomorrow will be the first day, when i'll use it.

Cons: i don't know, the batteries how long can be working, but i will know in the future. :)
no cons!!!!!

Other: it was a good deal!

Pros: The lock is sufficiently sensitive to sound at the right time. it is heavy and hard enough to not open easily without the key. The sound is impressive, strong, loud and continuous. I've put a bicycle while in the garage and is ideally suited to a thick tube of 6160 aluminum. You can put unarmed so that vibrations do not affect the alarm or jump, if we do not want full use lock function. The key is circular, so it is more difficult to open than a traditional key lock.

Cons: Perhaps the worst is exterior paint, it seems to be fragile and of poor quality, at least the finish of it is bad, but does not affect the operation of the system. At best, the batteries will last much, but I can not tell. There is no witness to indicate the end of the batteries and you can find that suddenly have been exhausted.

Other: I recommend this product.

Pros: Works nice, the sound is loud enough, you cant block the speaker like in the other lock, uses AAA bateries included inside, it says on package water proof and also I saw a gusket inside the batery compartment, but time will tell...

Cons: Sound can be louder, shackle can be thicker its about 8-10 mm, the lock is spring lock less comfortable and I think less safe

Other: good deal

Pros: very Easy to use excellent light practical for all kinds of bicycle gates doors bikes cars even good homes

Cons: rather long because I tried to put it in some corentes and he did not fit because your hook and a bit thick but nothing that changes the efficiency of it

Other: sorry but i did not this
