ZERO STARS! Cannot believe these have been priced at £70 odd quid! The frames are thin like wire coat hangers and mine wet bent out of shape so when I put them against the wall they didn’t lie flat. The ‘wood’ shelf is like cheap lightweight balsa wood.
There is only one hole to screw the metal frame to the wall so it ‘hangs’ meaning the bottom part moves and anything you put on the shelf had to be equally balanced. One of the shelves tilted down too so couldn’t put a candle on it as it slid forward. 
This item is probably worth £10 tops. Really REALLY poor quality.
