Bit of both really. For trackdays and the kitcar like you say it will be fine. Occasionally though I do work on normal road cars (15 year old never been removed bolts) where i have no power.

TBH Ive got a compressor and a gun but for the effort of getting it out and then the noise or hassle of turning it on and off I never use it and just get fucking knackered using a breaker bar and ratchet all day!

How long have you had yours Chip?
