Purchased the small greenhouse which was lovely quality. The only downside was the instructions were very unclear and it took husband 2 days to put together. One of the castors also broke before we had even used it. Love the greenhouse; but would never buy again as it should not be this difficult for assembly instructions. Husband nearly put the lot in the bin but persevered. The small pieces were not packed together so it took ages to count components and some of the larger components the sticky info labels had come off so we had to guess which part was which. Krypton Factor came to mind re; assembly. Shame as I was going to order the potting unit; but it is a definite no from husband. Please put instructions in writing as well as diagrams; especially when dealing with glass. There are pages of instructions and some instructions could be interpreted in a couple of ways, hence we had to dismantle some bits. The glass panel holes for opening and closing the doors, could do with rubber or something as you could easily cut your fingers, just needs a finishing touch. Despite the negative comment; we still love the unit and it’s an ideal size.
