To address some other reviews I got lucky here and didn’t have any missing parts or drill holes. My installation went perfectly! The only hiccup was getting the vernier in the back to fit into the assembled drawers slots. Alignment is tricky and it needs to slot in all the way down. Aside from that this is a great very sturdy unit when assembled and I’m happy with the product. As spoken of before having a power drill will provide a big benefit. Be handy and bring your tools and you’ll enjoy this filing cabinet’s quality. Assembly took about 1 hour.My only gripe was that the revised version I have includes 4 casters not 6 as in the product photo. This isn’t an issue but rather an improvement as it makes rolling it around on wood floors much easier. Also the casters include locks that are very effective in keeping it in place.I enjoy this and the set up time was worth it for a very decent quality product.
