With the slightest knock bottles slide forwards out of the rear notch. Fortunately I started filling from the bottom, so nothing broke. I altered the top to fit below a worktop, or I'd be returning it.

A bit flimsy, and bottles look like they can slide forward onto their shoulders and hence drop off the back rack onto the row below. I may have to brace the structure with further battens to feel completely confident in it.

Overall it fits together well. Be careful when filling the rack up as certain bottles do not fit properly, 1 bottle actually fell out breaking on the floor.

Bad design. As other reviews have pointed out, the bottles can slip forward and fall. When my rack was full, one bottle slipped at the top and caused an "avalanche" of about 20 bottles. Some slipped out at the sides. Fortunately, only one broke. I have fixed the rack by adding a plywood shelf under each row and plywood on both sides. It cost me £20 for the plywood to do two racks, but now they're fine. Would not recommend this product unless you are willing to modify it yourself.

Made of decent material, (pin?), but a bit flimsy. Easy to assemble. Does the job I bought it for.
