I've got a Rainbow. It's good at keeping the rain off when it's on and makes it very slightly quieter, but a pain to put on singlehanded if it's windy and it blocks my poptop vents meaning it's hot as hell up top if it's not cold outside. Only really of use if you're staying in one place, in cold/wet weather, with the roof up, for several days. I don't, so I used mine once and never will again, £250 down the drain.
