Okay... serious now...
The PaintPod paint doesn't cover very well - you'll need two coats minimum. That advert where he keeps painting the wall 'til the bird comes and shags him is complete nonsense.
PaintPod paint isn't like normal paint - it has a slight sheen. So, you can't do your edging with Pure Brilliant White and then paint the alls with PaintPod pure brilliant white...
The PaintPod is an ergonomic disaster area. If you lift the centre handle (to move it around) you can't then lift the blue cover to store the roller. The blue cover is also secured by two catches that require superhuman strength to open - again you can't do this when you are holding the roller. The power cord comes out as soon as you reach the top of a ladder... in fact any time that is really inconvenient.
The self cleaning process is shite. It is supposed to do it automatically with 5l of water - it takes at least 25 litres of water to get it reasonably clean. If you let the dip tube dry out you have to throw it away and buy another...
OK?
