I have 1 or 2 in inventory just for weird things can't tighten/loosen by one hand. Even then often won't work because size of "socket" alone.
Related is multi-size socket w/ thin layer that hex head/nut pushes in smaller layer in the socket.
Don't use any of them w/ impact drills or drivers no matter what ads or labels say.
Springs in them allow pins to move randomly as impact tool loads changes.
That is part of problems in many reviews.
Even w/o that issue, Yes Most to all won't work when need a lot of torque. When over-torqued the pins often fail and can make other problems. Related tool bend or break the thin layers.
Isn't just "cheap" made in China that have problems...
Stanley made "HEX-A-MATIC" (Long discontinued) and many others have made/makes "unverisal" nut drivers etc that can work but often have same problems.
While Stanley claim that fits 1/4 to 7/16 (and Metric in between those limits) needs same space as 9/16 thin wall socket to work so I rarely use one.
Side Note: Gater Grip and many others are/was sold on TV as "buy one get one" deals that are a scam because you get charge high shipping for the "free" unit.
Even when you try to order just 1, they won't care and send 2 and bill the high shipping cost because they get commission.
Any "warranty" does not return shipping cost and many times you have to pay to ship back a dead unit. Often will charge shipping for replacement too.
If you don't record the call many Debtit/Credit cards won't "charge back" if you file a complaint.
Similar problem w/ "Lifetime battery" flashlights etc... "Free" replacement battery cost 5x or more the value of the battery in shipping.
Very Few "Lifetime" battery offers don't charge shipping.
