Consumer Evaluations
Pros:
-It operates. Opening a window or glass door on which the alarm is attached will make it go off.
-It utilizes two AAA batteries which are widely readily available.
-It has a Low and a High sensitivity setting.
Cons:
-It goes off at full volume for a fraction of a second when it is turned on. This is unnecessary and disturbing. If you turn it on at night, your neighbors could possibly not appreciate getting woken up.
-There are various factors why this vibration alarm can go off, which includes sturdy winds, loud automobile horns (especially from trucks), and other peculiar loud noises -- even at the Low sensitivity setting. I say this from private knowledge. Do you really want to leave your dwelling with this turned on, knowing it could possibly alarm for no really good reason? Even if you intend to use it only when someone is household, even so, it is likely that you may very well sometime forget to turn it off when leaving residence. It might've helped if the alarm was either less sensitive or a great deal more intelligent, despite the fact that I know the latter is in all probability a lot to ask.
Misc comments:
-It does not turn off automatically immediately after a although if it has gone on (till the battery is exhausted). This may possibly be a pro or a con, but if it's nonetheless on following say ten minutes, it is almost certainly a con.
In summary, considering of the false alarms, I can not advocate this item. I trashed it, and opted for a GE magnetic alarm as an alternative.
Works as advertised -- loud, too! Apparently they anticipate you to install the sensor perfect in the middle of your window if you want to use the low setting, any place else and they suggest you use high. I stuck it in the corner of my window on high, and it is sensitive adequate to go off when we get a close sufficient lightning strike, but not so sensitive that it is going off with every storm. We've had LOTS of thunderstorms this summer and it only went off once, so I consider that a great balance in between becoming sensitive adequate that I am confident in it without getting annoying from too a number of false alarms.
