My friend purchased three of these and I put them together for her. With the first two I used only a screwdriver and the Allen key provided and found that the handles don't screw on tightly because the holes provided are not big enough. For the third one I used an electric screwdriver and they went on perfectly without any hassle. Otherwise these pantries are perfect. I plan on buying some for myself.
This took me about 1.5 hours to assemble (alone) and it was pretty easy. The only thing I'd suggest is to purchase a few washers for the handles because the screws provided (to attach the handles to the doors) were too long and even with every ounce of strength in my body I was not able to screw the screws into the handles all the way so they jiggled. So I installed washers to provide a tighter fit. Other than that, this is a great product!
Was a little hard to build but we've been using it for over 5 months and it's perfect. I saw the other reviews but we had no problem with the handles.
