Yes, I cleaned the surface and waited for them to set in place before testing them

It says to stick them on a clean surface, we did

Perhaps it's our fairly-mundane custom cabinetry but there isn't a straightforward flat surface on many of the cabinets to adhere to

Took about two minutes to clean the surface, as other reviewers suggested, line up and stick on

Make sure you clean the cabinet surface where you intend to place the sticker to ensure a good seal.

The installation is "easy" in that most cases don't requiring anything more than two clean adhesive surfaces, but getting everything to line up perfect in both the x and y directions is not straightforward

The adhesive sticker didn't hold on several of them long enough to drill (yes, I cleaned the surface per the instructions), and 2 of them didn't latch on at all after installation

every penny.*tip* I applied rubbing alcohol to clean the surface first before sticking them

They're easy to install, but please make sure to clean the surface first

Fell off in a couple of days with no one around -- and, yes, I cleaned surface before and applied correctly.

Would be to clean the surface as directed

This should be obvious: It is important to clean the mounting surface WELL or the glue will fill with dirt

Adhesive surface is great, no need for screwing these in.

If you pull slowly, it works as it should

It was a hit and miss as in some cabinets it would hold in others not so good.

They work as they should!
