After i put it to the test I was thoroughly impressed with this hexagonal socket driver. It is durable and perfectly fits the bolts I needed to tighten .The handle provides a comfortable grip and makes it easy to control. The only con I can think of is that it is a bit expensive, but you definitely get what you pay for in terms of quality. Overall, I highly recommend this tool for anyone in the industrial and scientific field..
Been looking for a similar product for weeks. The only thing I would like is to be able to get them in both standard and metric versions for 1/4"-9/16 and 6-15mm.
