After a few inquiries on the internet and compare with Amazon, I ordered the iFixit set. Important to me was a high useful tool. In other words, if I want to solve a stuck screw in miniature, is then the bit / tip not twisted equal and be unusable. The shipment of Amazon as always, quickly and easily. Receive, unpack and immediately to the object. So far I have thus opened and closed a digi-cam and a wrist watch. The slotted screws (salt water, sand, dust) and pretty underwater Especially with the clock were determined by use in several vacations. The first thing that struck me positively: in hand, at least in my, the bit holder is excellent. By 3 rubber rings, it can be just as precise and keep right and turn. After working with the clock I've looked at the two bits used accurately and despite power use during assembly / spinnig I have no material changes (bending, breaking) found. This was in advance benutztem DIY tool (for a quarter of the price) significantly different.
Since I have not used all the bets so far, I can speak Torx bits only for the small slot and but of this I have not been disappointed. For this reason I am using the price-performance ratio (below 30, -) very satisfied and would recommend this set.
