First off this set is VERY small - like the entire box is little bigger than a pack of 20 cigarettes, so it isn't for big tough jobs, but having said that, the ratchet spanner looks to be strong and is beautifully made! It's worth buying this set for the ratchet spanner alone! It's just that I would not recommend using it on jobs that need plenty of "grunt".
I was recommended to buy this set by a gas fitter who came to install our new gas fire. He had to fit a cover screw on the fire in a very tight space and produced this set. I was immediately impressed as the space he had to get in was very tight indeed and no right-angled screwdriver would had fitted, but this ratchet spanner did, so I bought the set - and glad I did! I've used it on several awkward access jobs already with great success.
The rest of the set is nothing overly exciting other than a well-made set of various commonly used 1/4 inch hex bits, a hex to square adapter, an extension bit holder and five metric spanner heads - for which you need the hex to square adapter. See the details in Amazon's description above for details of the hex bits included.
Recommended for getting into those really tight spaces with a decent screwdriver.
