Has a good and stable plastic cover which keeps all of them very tight in the position. All balls and the springs are well adjusted so no problem on the connection. I am not sure about the black coating but it looks very good, I dont think it will peel of easily. Well done 👍🏻 Price is ok 👍🏻

Item is as described. Case keeps the three extensions secure. The extensions are clearly identified, quality is fine, heavy sockets will fall off if you are not careful, but considering the price they are a great deal. I would recommend them for others.

Mine came covered in some kind of grease/oil and they are a loose fit on my ratchets. Get what you pay for i guess.
