This review is a partial opinion before painting real test. It contains only the first comments on the product and allow you to get an idea. the -: the device does not allow the use of a standard roller. It is specifically designed for this machine roll and there is only one supplied with the unit. From experience, it is often useful to have several rollers. In addition, the roller does not roll freely. It seems that it can only be operated when the machine is in operation. Finally, this machine can be a useful addition to a paint gun for the realization of large dishes. The tool is average bill (it's Bosch) and would not be suitable for professional use. This review will be completed very soon because we have in anticipation painting.
