I purchased one of these as a gift for my father in law, but was a little wary based on some of the negative reviews here on Amazon.
when it arrived, and I had a chance to properly inspect the contents, I was impressed. So impressed in fact, that I bought a set for myself!
My set has now seen use in a variety of situations, mainly involving fitting timber guardrails and battens in my loft. At all times these screwdrivers felt comfortable, secure, and strong - I can only assume that those reviewers who experienced issues need to lay off the whey protein and develop a more gentle touch.
The case itself isn't the most robust thing ever, but it's also by no means flimsy. I accidentally stood on one corner of mine, and 18 stone of northerner only managed to produce a small split in one corner.
So if you need an extremely useful and well organised screwdriver set, you could do a lot worse at this price.
