A quite weak wheel that moves with great pressure. It is definitely not suitable for professional use, only for occasional use.
Nonexistent support from the importer in case you lose something or it breaks.

Quite good for its price. Necessary condition to change the disk of the packaging with a better one on the market. As for the negatives, a. it heats up relatively easily but the thermal saves the situation b. it needs a small modification so that the water hose does not come off. This is after 10 days of use and cutting an old reinforced hard plate of 10cm
