    Good security alarm

    posted by sailamaarit on 02/17/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Loadly enough to be effective anti-theft security alarm. Prevents thefts of bikes, but can also be used as security alarm for example at home door because of high dbs. In principle good alarm. very easy to use. Just put 9A battery in, then key in and turn i...
    Cons:
    But, there are also worse ones among these alarms. 1/3 of these alarms did not function because of broken metals or cables insi...

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    I bought this bicycle alarm to scare the thieves. It has a good sound intensity, not very loud but it is OK. It has a key, which is better then the models with a code because you don't learn any codes and the energy consumption is lower. The batery (not in...
    Cons:
    Poor quality material. it is very fragile. not waterproof. i think that if you are a thief and hit the alarm with something it ...

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Reliable operation, deter the stranger. Reliable operation, deter the stranger. Easy to fit small space. The item is out of reach.
    Cons:
    Simple design. All products use the same key. I think you can not 120 dB, 90 dB is about the real volume. No delay, thus openin...

    Works perfectly!

    posted by MarlonAtDX on 12/24/2011 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    Very loud, and good, usable, locking system. Also very sensitive, so don't touch your bike when it's activated. This has actually a nice effect, I have it on my bike and someone tried to steal my bike the other day. The alarm went off and he ran away! So, w...
    Cons:
    Did not fit well the first time, and is not waterproof. Needs some 'Do It Yourself', and make sure the 9V block doesn't hit the...

    Cheap bike alarm

    posted by poulman on 08/04/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    I bought this bicycle alarm as a replacement to another I had which was activated by three buttons (ABC). The previous alarm consumed the battery very fast, even when it wasn't at standby. This one has a key, so it is totally switched off when not needed. ...
    Cons:
    I was very disappointed by the siren. It's unbelievable weak. Its noise isn't noticeable from a near distance. Also, there are...

    One word - PERFECT!

    posted by dexuser on 06/30/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    - VERY loud (multiply that by 100 times). This is good. - Thief cannot disarm the alarm without the key - Smart circuitry inside prevents shrill alarm from wailing continuously the whole day when activated, thereby helping you to save battery life. - Compac...
    Cons:
    - None in my case.

    Cons:
    The building quality is terrible and the material used is really bad. One of the alarms arrived with stuff inside broken and d...

    Cheap & actually useful

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
