Happy with mine. Takes a minute to fit as a two man operation or perhaps 2 as a one man exercise.
I hate wet items in the van, the pucer virtially avoids this. Just been in very heavy, near torrential rain on the portuguese coast. Kept the roof dry so we could lower the roof when the rain subsided without having wet bellows to contend with. Once off I dried it with a towel on the washroom.
Very handy to keep the top warmer, quieter and less like a draughty tent too. Only weakspots are that edges are lined in canvas which retains moisture after rain. A minor issue that does not detract from the benefits.
Also it rolls up so takes up boot space, but it is light. When we park up we either use it (if cold or rain expected) or we leave it on the dash so either way it does not intrude on the living space.
