my weekend job in B&Q, we have lots of nil returns comming back, due them basically breaking down in some shape or form. However i have heard some really good comments about them from other customers, seems to be a mixed bag.
As for the paint itself, i really cant see this been solt a year down the line, as its not that popular and people will be stuck with the machine. Also you cant use normal paint, as it gets clogged. Few customers have washed out their pot and put normal paint in there trying to water it down, no joy.
£1.97 roller set. Throw away when done no cleaning is the most popular option
