Query: Cheaply made, sometimes works

I had to throw this away after trying it. It looks good in the photo but it is flimsy and unreliable. Sometimes it would work when moved; other times you could slam the door and even shake the alarm and it would still be silent. So if it can't be counted on to work every time someone opens the door, it can't be counted on at all, right? Don't waste your money on this one.
