As per other reviews, the assembly instructions are a joke. Once you get it sorted the lock screws work well but having to put in the drawer runners blind was a challenge. Mine had a defective runner – apparently a replacement is on its way – the jury is out on whether it will fix my problem. Mighty Ape have been great in helping so here’s hoping. Couple weeks later the problem has been identified by my very handy neighbour. Mighty Ape this is a great product seriously let down by the dreadful instructions. Fix that and you won’t need to special it.
