Since the size is described on the outer circumference, it is convenient for taking out. Since the socket part is a Frank Drive, it does not scratch the bolt and the usability is excellent. However, the hold feeling is still inferior to the snap, but the cost performance is the best
I think that the brand products are moderately good, although there are many well-known manufacturer products, they can be used equally, as usual. Can be used without bending licking bolts and the like which have been consolidated, and may be difficult to lick. It's not expensive and I'm satisfied.
