Price and rating as shown on Amazon when we collected them. Both change.
The Bosch PEX 300 AE is a corded 270 W random orbit sander with a 125 mm disc, supplied in a case, and it takes fifth place in this guide at £79.56. Its Amazon listing carries 4.4 out of 5 from 1,193 ratings, and of the 100 ratings plotted in the breakdown, 67 sit at five stars and 21 at four — very little weight at the bottom of the scale.
The number worth stopping on is the amperage. The listing's amperage field reads 270 Amps, which is the same figure as the motor's 270 W. At the 230 Volts the same listing quotes, a 270 W motor draws roughly 1.2 A, so that amp figure is out by a factor of about 230 — the pattern this guide warns about. A second field sits oddly too: the dimensions are given as 38.6 x 29.1 x 14.8 cm for a 125 mm sander supplied in a case, and the listing does not say whether that measures the tool or the case. Everything on this page comes from the Amazon listing, not from testing we carried out.

The listing's amperage field says 270 Amps, but the same listing gives the motor as 270 W at 230 Volts. At that voltage a 270 W motor draws roughly 1.2 A, so the amp figure looks like the wattage entered in the wrong box.

The listing gives a disc diameter of 125 millimetres and a grit rating of 80.
