Use a drill, there are so many screws. Takes a while to put together, more pieces than I realized. Read ahead in the directions so you know which end will be the top. We got two to put back to back and 1 end against the wall. By the time we realized one end was wrong it was too late to fix, but for us it worked out because we just put that end against the wall. The second one went together much more smoothly.
There were a couple spots where the screws pushed a bit of the particle board off so there are a couple chips. This isn't my permanent solution for storage, with my 2 large dogs, 1 still a puppy who chews, and currently 9 cats, anyone want a kitten lol. This will get me through until I get to remodel my kitchen, and will keep it looking decent in the mean time.
