Works pretty well... three and a half stars well...

The thing is with this thing is you need to get it right. People seem to have a lot of trouble with these but they do work if a little slower than you might hope. The surface you out them on shouldn't be a cold one, like a cold car roof, stone or damp ground since it sucks the heat away. Also a decent breeze will cool the dark surface and make it less effective so somewhere with a bit of wind shelter is also preferable. All that being said these does work.
As you'd expect the flow isn't amazing but you can easily wash with it, or take the hoze off and just hang it up as a water tap which is incredibly useful. Some people also seem to have issues with the flow, I don't know but I experienced something similar when I turned it all the way "on", but if you tweak it back a little the water flow hole lines up and it flows great. Also the little red tap slides up and down and needs to be pushed right down so as much of the attached red tube that you slip the hoze on to is visible... Otherwise the flow hole doesn't line up. I'm guessing it has this movement so you can take the tap part out to clean the separate parts which is a good idea!
Regarding durability it can be carried and hung when filled completely, however after five days of use the handle has started to stretch a little so it won't last very long if you do fill it completely then hang it. If you have a net bag to put it in and then hang that up instead however - problem solved. I'd give it three and a half stars but I'll round it up to four since it is completely functional, but could be constructed better.
