In the last 4 months, I've had 3 of the 3/8" drive, 15" Sunex impact extensions fail 3 different ways. (Sunex part number 3515)
First one shattered in half when using it on an MG325.
(Didn't keep it nor take a picture)
Second one, the detent ball came out; never could find it.
Third one, the dentent ball is stuck in the downward position and won't spring outward anymore.
Is anyone else seeing the types of failures in daily shop use?
OTOH, I haven't had a single failure of any sunex impact sockets and they take a beating in the shop.
Anyone know a usa manufacturer of a 15" 3/8 impact extension? I really like the size but it seems the 15" length is an odd size and no one else makes it.
