Well engineered and very solidsturdy. Really pleased. I was able to put two together by myself. To the mfg please change the stickers. It’s great to have them to identify the pieces but it was a real pain to get them off the wood pieces. For buyers look ahead to the next step as the pieces do t always go as you assume. For instance the two vertical pieces are different and of you don’t get the correct one on each side you have to start again. Also, I’d recommend loosely tightening bolts at each step until you get the alignment the way you like it. There’s enough play in the holes that shelves can be slightly misaligned (by a mm, but some of us care) if you just tighten one at a time. 

Overall I highly recommend.
