I love what this thing has done for my kitchen and I will probably over time get more of them so fix up this whole place and make everything more functional. That being said, I didn't know I was going to have to use a power drill and they scare me so I avoid using them.  There was no around it, holes had to be drilled into the cabinet floor. I had to talk myself into it, but once I committed to it, it was fine. You have a guide paper and you only have to drill 4 holes and then really I did manually screw it down after that, but if you aren't a scaredy cat like me you will probably just change out the drill bit on your power drill and screw it down faster. It's important to know, especially if you are a single female living alone what you're getting into though, so there you have it.
