Just bought the 49pc set with less filler fluff. Figured I would give it a shot. Possibly destined for junkyard/road box. God knows we all need more 1/4 and 3/8 sockets
I can see some distinct advantages and disadvantages.
If you have a favorite drive tool/attachment, chances are it is not usable here.
Ratchet wrenches of any kind do seem to have torque limitations, may be wise to break free with another fixed tool first. (same with any gearwrench)
I would like to see a spark plug socket in this configuration for low clearance apps. (mostly cam-in-block cars/trucks)
The sockets are extremely thin/light which will be more prone to cracking.
They are 6 point, and carry the same pros and cons, including not working on 12pt fasteners.
They are a little wobbly since they are retained by a thin snap ring inside the gear wrench.
They may easily be pushed out of the drive handle.
Pros
They are 6 point, and carry the same pros and cons. With 6 drive surfaces and 72 teeth there is not much excuse for limited approach angles like old coarse ratchets and 6 point sockets.
The sockets are extremely thin/light allowing them to fit more places and travel lighter.
Allow long thru bolts just as obviously stated by design.
Easily pushed out of drive handle.
As you can see, many aspects could be both a pro and a con depending on the specific situation.
Main use would seem to be moderate/light torque on 6pt fasteners located in tight areas or carried in travel boxes where space/weight is limited preventing carrying deep and standard sockets. I can see a few places where the fat extensions may be a hindrance.
Got it to streamline a travel kit, and believe it may serve that purpose.
