Plastic is too brittle so difficult to tighten screws sufficiently
on 24 June 2014
Unfortunately as soon as I tried to screw this alarm to my bike frame the first screw head simply pulled through the plastic (no washers are included with the nuts and bolts), and when tightening the second, even very gently given my earlier experience, the nut pulled through the plastic the other side! A circle of plastic simply popped out of the moulding as the nut tightened, and of course rendered the alarm useless since a thief can now simply pull the alarm off the frame! I appreciate this is about as cheap an alarm as you can buy, but I didn't expect the plastic to be so brittle. If it is this brittle then including washers would help avoid this issue, but the screws that come with it would need to be a tiny bit longer to allow for washers both sides (there are much longer screws included too, but so long they would look quite weird sticking out quite some way). No idea if the alarm does its other job well as never got that far.
For those unaware, this alarm also needs a 9v battery (not included), and if you want to change the code on your alarm to one of your choosing you simply take the battery out, then type in the default code ABCA and then your own. If the alarm was going off you could also just remove the battery, so basically this seems to offer a thief about £3 worth of aggravation factor i.e. the same amount as I've had already with it as the bike owner.
