As a seller they are very good but the product I recieved,nearly cost me a divorce,.. two cloches!!! For the money they were very expensive with very limited instructions,they don't tell you that there are 2 screws for the top and 2 different size screws gor the bottom!! And because they are mass produced the metal is pinched together,so the plastic sheet doesn't fit properly...so I had a problem getting in the hole!, once together they are very sturdy but holy Mackerel, you need the patience of a Saint and abot 6 people..its like twister for gardening I also think they need to lower the price..
