I used the magnet locks for my DS about 12 yrs. ago and I LOVED them. I think I kept one on the fridge...and a back up magnet in a drawer. I was mostly worried about the cabs. down low ...(that held cleaners, etc)
I remember my ex complaining about drilling them/installing them....but once he had 1 done, he copied the pattern for the rest, and installation went pretty smooth.
We LOVE the magnetic locks! My DH did not like the idea of drilling in the doors for the traditional locks.
In the kitchen we keep the magnet on the base of our sink.
In our bathroom on the light fixture.
We have the adhesive magnetic locks and for the most part I like them. I really like them because you can turn them "off" if you want to. For example, I had one on the trash pullout because DDs were into that for a time. However, I would just turn it "on" if they were in the area/bothering it and therefore it wasn't a problem most of time. For the most part, they have ignored the cabinets. I have had problems with the latches pulling off however, particularly if DH forgot there was a lock on a drawer and tried to open it. We keep the magnet in a drawer stack of kid stuff we have on the counter.
We do have different locks for our pantry and under the sink (ones that attach two handles together).
