I bought the harbor freight electric 1/2 impact about 2 months ago and Very pleased with it . Cost me $39 with sales ad coupon . I've did 2 lowering spring jobs and many wheels on an off with No issues ! We tried my buddies Brand New Craftsman cordless 1/2 impact and wouldn't break a lug nut loose .
For the money it's well worth it . Only draw back I have is once you push the froward/reverse button it's not variable speed.. Its wide open ! Just be careful when the lug nut comes off . Tool keeps spinning...
