My only concern would be their stability in the wind .... would they have withstood the last few days
I have a Redmire one which is timber and on skids so it movable, I am extremely pleased with this and would thoroughly recommend them, however if you are looking for the type from the Comany you asked about then this may not help you
They claim they don't blow over if properly secured..(well, yes, of course!!). Actually I have just found a little company half a mile up my lane..never knew they existed! I think the chap will build me what I want. Looking at a 15.1hh this w/e and will need some extra cover until we move...
