Rated 5 out of 5 by Excellent quality bit There are a lot of Pozidriv bits out there, but this range by Wera are very well made and tough. They are accurate enough to be able to carry the screw on them to the hole (all Pozidrive bits should do this, but a lot of them don't). They are tough enough to withstand cam-out incidents (which shouldn't happen but sometimes do if you're not applying enough pressure) without damage, which would compromise their future use. Price is a bit more than average, but you get what you pay for - you don't need to buy a number of them to be thrown away as they wear out. 18-Oct-2014
Rated 5 out of 5 by Only the best These bits stand up to do a lot of work. If you buy cheap you will go through them in no time, making them more expensive in the long run. 21-Aug-2014
Rated 1 out of 5 by Quality? Managed about 20 screw before snapping off! I use quite a few of this type of thing (I find the 50mm ones particularly usefully) and would gladly pay that little extra for a quality item. This last far less than my normal quality item not a quality item, very brittle. 06-Mar-2014
Rated 4 out of 5 by Last A Long Time The few of these bits that I have bought proved very durable. I haven't worn one out yet only replaced a lost one and lent them to other people. They will only 'cam out' on worn screw heads but if you press harder and slow start you should be OK. The price is fair and one of these will outlast many cheaper alternatives so they are good for regular DIY 13-Feb-2014
