It might only be the difference between a 17mm being 17.05mm on a Stahlwille or Toptul compared to 17.25mm on a cheaper Chinese Gearwrench, but it does make a difference, doesn't it?Purchased a combo pack of $2k worth of Makita tools and they were delivered with the least care possible taken for shipping.I expected to pay around $1400 for the kit,
