I bought two of these and they have done the job. No pigeon demolition of my brassicas this year. I can get in and out when necessary to do the weeding but as I have chronic arthritis the entrance is a bit of a struggle. The dor strip is not easy to use and I worry about tripping. Also, I needed help as it is a bit of a marathon with the myriad of screws to fit. I would have used a magnetic tray if I had thought it out properly before I started. I used steel ground supports on each corner for extra stability. But there is no doubt that this is an excellent solution to my battle with the pigeons. It is lightweight and manageable too for someone like me. And it got the thumbs up from my allotment neighbours. I am very pleased with it.
