Just a good size, easy to grip and tightened securely. I bought P1 and P2, but if P3 is also available I will be saved for tightening in a narrow place. Although there is no problem in function, the picture of the product was different from the actual thing.
Ideal for detaching screws in narrow places when disassembling / repairing products. Since it clears the point which is troubled if it is not with magnet for use, we chose this product. Hopefully it will be a bit cheap, but is it too luxurious enough?
