Review on Upgrade Your Impact Game With KAIFNT'S 12-Piece Hex/Allen Power Bit Set And Magnetic Holder by David May

I bought this set because I needed them to change the mass air flow sensor on my car. I bought these in March but it wasn't warm enough here in ND to change it until May here.When I tried to use these to get the mass airflow sensor out they won't even work! The whole wasn't big enough to allow the torque wrench to get in and turn it! I ended up going to A-1 Auto on buying a different set oh, what they should have done in the first place because these are worthless! And now it's too late for me to return this worthless piece of garbage!If I were you I'd go to A-1 Auto or someplace like that and buy a set and save yourself a time and money of ordering this set!
