The local surf shop here sells a ton of those and the guys that work there have them too. I haven't used one, but I like the concept.
The issue is you can't add press to it and it'll only hold it so long. Would be nice w/ a pump but then you could just get a garden sprayer and add a nozzle like a link above did.is it a turd ??
saw the video on something else I was looking at -
