Solid once mounted BUT check carefully that above the door where you want to put it down, you actually have enough room to hold it properly. This is not my case and it was not possible to me to keep it above / behind / in front of a door so I could only use it on the floor, my mistake but beware, if you read this opinion, you are warned. I think we have about 8cm (at least 3-4 more like home) to be broad.
