I used this unit to lift and drag/carry 40' long I beams and it worked fairly well. The handle configuration limited how I could attach to the steel as the flanges conflicted with the travel path of the handle. The unit is very heavy! I don't believe that I got the holding power as advertised but I was lifting galvanized material and that could reduce the power and the 1/4" thickness of the steel was not the best for magnetic hold so overall I give it 4- not 5 stars.
