Now back up to £100! Fantastic little drill for the money though. I bought one last week and am well impressed so far. Small and light, but still has enough power for most household jobs (get a corded hammer drill if you want to drill into brick, concrete etc).
That blue 10.8v Bosch is ok but a bit weak; it’ll struggle into anything dense or thick, or using larger bits. More of a screwdriver really.
Here’s the same Bosch as mine, in John Lewis’, for just £67:
