Having the electric impact literally knocked 45 minutes off the time it takes to properly swap the tires on my RS for winter.
it was so nice to just zip the lugs off without having to hand loosen everything while the tires are on the ground, and then ratchet them off.
And the Auto Stop feature is fucking amaze balls. It'll stop as soon as its hits the first Ugga Dugga. I put finger threaded the on, then nascar style ran them down on Auto. It put each lug at roughly 50-70 ft-llbs. All I had to do was roll around to each one with the ratchet and I only got about 15° extra turn, which is right around 100ft-lbs with my 1/2 Ratchet.
And my back hurts nowhere near as much as it usually does when I have to manually do it with the ratchet.
