I was sent this roller by a company called iconicwalls.co.uk
They sent me it for free to try out.
I must say I was converted straight away and will be using these from now on.
They are quicker than a brush and more accurate.
The roller is by Painto and can be found on iconicwalls website.
It's the future and not at all a DIY gimmick.
This is the way to go for professional decorators.
