What has, however verhagelt me the day that this bit holder, or rather the depth adjustment, one day was a loud crack and has many small, flying debris broke down.
Apparently the screwdriver was a little too strong and set the depth adjustment had moved to, otherwise I can not explain.
Anyway, I could no longer use the bit holder for the drywall screws, thus I use the holder only as bit holder. Drywall screws I have in the near future anyway not fix, so the loss is not so tragic.
Again I would recommend this product, however, is no longer for sale.
