Have been looking for a cheap retractable hose reel for a while, this is about the cheapest I have seen. Usually the cheapies come with 10 metres of hose however this comes with a reasonably generous 15 metres. Cannot comment on quality as have not seen this brand before.
Only cheaper one I could find was here http://www.crazysales.com.au/wall-mountable-retractable-hose… however this was a 10 metre hose.
Looks like the colour is fluro green so you don't loose it
