I can't use them on double-glazed windows. Money wasted.

The grilles are quite alright, a really good invention if you have cats. What bothers me, though, is that even though the description says you can stick the grille on, it doesn’t actually work, not even with the tape mentioned in the product description. It just doesn’t hold – the grilles gradually fell off, and some couldn’t be stuck on at all because the little metal plates where you’re supposed to put the tape aren’t welded on straight, so you can’t really stick it properly to a flat surface. So even though I didn’t want to drill into the windows, now I have to. Considering all that, I think the price is too high.

Easy to install, they're safe for our tomcat and we can relax knowing that.
