  • Good for that price

    posted by dule82 on 01:08:40 G6T 10/06/2014 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Price - Extra High Noise - Easy to use - No need for manual - Quick activation/ deactiation

    Cons: - No battery - Unable to unlock alarm without alarm goes on. - Quality - No screws

    Other: Good for that price, excelent in fact. But there is no way to unlock it and deactivate it without sound beeeep :). Anyway, nobody can touch it with anything so there is a good side of it. No screws and battery and is on a down side, but bottomline is that product is more than good for current price, and everyone can have it on bike or even on doors.

  • Good security alarm

    posted by sailamaarit on 19:04:56 G2T 17/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 it to the right direction, to the green area.

    Cons: But, there are also worse ones among these alarms. 1/3 of these alarms did not function because of broken metals or cables inside of these boxes. About 5 pcs among 12 pcs which I bought were broken.

    Other: Easy to use, loadly enough alarm at nice price, but broken ones among these black boxes.

    Involvement Level: Expert (understands the inner workings)

    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 included) it last very much. I have this product for over a year and stil works with the firs batery. It has two level of sound. when it is first time activated it sound for five second and then hi stops. if it is activated again it sounds until you stop the alarm with the key.

    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 breaks and it stops.

    Other: it is good for scare the thiefs

    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 opening an alarm. I am a bit disappointed, but if you watch the price is not reason to complain!

    Other: Good product. A fit for purpose, easy to use device.

    Involvement Level: Expert (understands the inner workings)

    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, when you have this/buy this, you can go without worrying about someone stealing your bike.

    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 metal thing. It shortcuts when you do, stick a piece of paper in it, and you should be OK.
    Also, it looks larger on the pictures.

    Other: This is a must have for many people. If you also have a normal wheel lock, attach the keys to it as well with a cord. It's so much easier then.

    Involvement Level: Expert (understands the inner workings)

    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. Another good characteristic of this alarm is that it has a metal bracket that can be bent to fit most bicycle bodies. It's also small enough not to bother by it's size or appearance and I like its design.

    Cons: I was very disappointed by the siren. It's unbelievable weak. Its noise isn't noticeable from a near distance. Also, there are no screws included. No way to screw the metal bracket to the plastic cover. The plastics are cheap and fragile. A thief could easily make it silence with a good hit of a hammer. The keys are very fragile too. There is no delay from the time to insert the key to the slot to the time the alarm rings. That's annoying. It's certainly NOT waterproof. The electronic board inside should be put in plastic or rubber cover in order not to be ruined by water. Finally, there is no manual at all.

    Other: If you like cheap electronics like I do, this alarm fits your needs. It's very simple and less consuming. It can (with modifications) be placed anywhere. If placed on a bicycle, you will be notified when someone tries to steal it, as long as you are near enough to hear its weak siren. Try not to leave it in direct sunlight in the summer, nor under rain. Its plastics are very poor and it's not waterproof. At least, it doesn't consume battery neither at standby, nor at off mode, like other alarms do.

    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.
    - Compact shape fits nicely in the palm of an adult's hand. Can be mounted anywhere, not just on bicycle.
    - Can be used to guard your laptop or notebook while you step away for a moment. You can see a demonstration of how this can be done in my youtube video review which will be posted shortly following this written review.
    - Simple design without complicated electronics inside means that it has less chance of breaking down. As long as the solder joints inside are well soldered, this alarm should be able to last you a long time.

    Cons: - None in my case.

    Other: I liked it so much I bought a few more just in case it gets sold out!

    Pros: After some complains about delivery of the product I finnaly got 2 of those alarms. Both came with problems and did not work. I was tired of complaining about delivery so did not complain about geting a useless and broken product.

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

    Other: I do not reccomend this product. Very cheap for the proposed idea but at least with me did not work..........
