I had a simple before this bit set from the hardware store. It also fulfilled its purpose, but went to a short time broken. The bit holder and the bits stuck took off very quickly. Now I wanted to have a decent bit set and have bought this set because of the product description and reviews. It differs optically not very different from other sets and is conveniently packed. The bit holder is very well made and you can change bits quickly and safely. Bits per se appear to be very hard and to show up today despite intensive use only optical scuffs since the paint in some places is from. At the material itself, I can still find no wear. The current price is a bit overdrawn in my eyes, but I can recommend the bit set fully. In normal circumstances it should be enough for a living.
