I like it. Only cost a fiver when I bought it so great value.
Just remember a couple of things.
It comes with an attachment that stops the water flow, so bung this on one end or all the water flows out the end, not through the perforation holes.
Attach to your tap, but use a normal hosepipe here then join it to the perforated hose (joiner supplied), or you end up watering your wall, pathway, whatever until you get to the garden.
Turn tap on full. The pressure is needed to force the water through the perforations.
Thats it. Once set up its a doddle. Just need to move it around a bit when the water is coming out to get it all going in the right direction.
