Bosch PSR 14.4 LI

You don’t need muscles for this Bosch, which was one of the lightest on test at 1.15kg. The low weight is down to its limited features; a single speed, maxing at 450rpm, no hammer and only a 10mm chuck, although it shared the LED light and illuminated arrows with its PSB sibling (below). The screwdriving was great, but high-speed brushing less so, although the Li-ion battery had no problems. A bit limited and quite pricey.
