The label with the respective size "Lasertip" -Dreher pack the screws unverrutschbar, an excellent idea of Wera. Even if one shakes the screw harder tackles, crunches, slides or groans nothing. Even almost "rundgelutschte" or highly swept screws can be thanks to the "Lasertips" boring well, if necessary, can be a bit of hit a slight notch in the can take the Dreher. This is to me so far so well with any other spin.
This kit should be in every household. The most common sizes are of high quality available, even including electrical Dreher
Voltage tester not missing - in as good a quality.
A magnetization of the spin would be the icing on the cake - this facilitates one-handed screwing. However, you can help yourself a little by gently presses the screw when placed on the spin, tilted slightly and balances - the Lasertip goodness.
5 stars for good quality and consequently a strong buy recommendation.
