Well I rented one from orileys and the plastic handle broke inside my cheater bar. Plastic!!! Why the heck would you think oh let's put a plastic handle over the guts of the torque wrench??? Anyway fell short everywhere else I called for rental. So i used my so called 700ft/lb. Kobalt air tool to tighten the rest of the u bolts down. I did get the first one torqued i used the rental on to 250ft lbs according to their wrench before it broke, then when I went for a second click on it boom plastic busted inside my cheater bar. I did torque all others to 150ft lbs with the torque wrench I own. Then when I busted out my air tool it didn't move the one i got to the supposed 250ft lbs, but it did move all the other ones past the 150ft lbs spot I had them to. So my air tool when hooked up to my 6-8 gallon Hitachi roofing compressor it doesn't have the 700ft lbs it claims to have . But I'm just gonna call that good and after a month of driving it I'll bust out the air tool again and give them some more love for the heck of it. I don't think they are going anywhere.
