Pros: price is good. Seems sturdy enough. Size is nice. Easy to hang on wall. Cons: be prepared to paint this cabinet. it’s primed only. There is no finish coat. Looks kinda rough, Dirty and unfinished. A coat of paint will fix this issue. Install was a breeze until I got to the backing of the cabinet. You have to nail 20 finish nails with this dinky little hammer that’s provided. I was actually cracking up laughing the whole time cause it felt so silly. Took a long time with the toy hammer… once I got my real hammer all was well.
