Grunty lil sander. Very comfortable to hold.

When you first use it you think its great. Then after a few sessions of sanding the dust starts seeping out of the filter box despite it being empty. The sanding discs then stop adhering to the base and go flapping around the room. The sanding discs stick to my Metabo sander so why they dont stick to this beggars belief. Hubby already returned one and now about to return a second one. 6 year warranty on a product that cant handle 20 hours of sanding. What a joke. Zero access to Bosch customer service in NZ and hesitation to replace or refund by Mitre10 adds to the annoyance of this product.

Backing pad loses its stick ability very very quickly. Unacceptable for a professional unit to have sanding discs fly off after less than 20 hours of use.
