I found it a royal pain in the harse. Blows out, times out, to hot cut out - it was always bleeding out! I didn't bother to set it up again this year. Besides, it just wouldn't be reliable enough in the snow, if it cut out you would have a frozen hose - you don't realise it has cut out straight away and the pipes would freeze.
On the other hand, it taught me how good hot water was and that you need a proper one. Or, even if you diy, you need a better solution than the l5.
Mines one is up for grabs with a british gas attachment if anyones interested, its had about three weeks use. Comes with an empty gas cylinder. Oh, and the hoses are standard too. (that was one of the biggest hassles, finding hoses that fitted it).
