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.

What buyers actually say

Quoted from customer reviews on Amazon

Verified purchase

“We've been using this sander while we're renovating our Victorian house, and it has worked very well so far. On the walls it leaves a smooth, even finish, and on the wood of the doors it has been quick and consistent. It feels steady in the hand and the vibration is controlled enough to make longer sessions manageable.The dust collection isn't perfect, but it does reduce the mess, which already helps when working indoors. The machine feels solid and the movement stays stable even when we need a bit more pressure.Overall, a reliable and easy-to-use sander that gives clean results on both walls and wood. A good choice if you want something straightforward that still delivers a neat, consistent finish.”
