Wishing they made wobble extensions.

I’ve been happy with my impact extensions. A little bulky but have held up well. No experience with the crome extensions
Nothing special but usable warranty handy on extensions as do get broken at times .
they chunky type with light knurl, much same as in house brands like power torque etc .
Hard complain at price but if fussy on fit diameter rigidity and knurl you may want shop around little more .

I bought a few to round out my 1/4 drive at home. For that very light use, theyve been fine.
I used mine the other night along with a few others (CM USA, Kobalt USA) to try to find just the right length to get a nut tight on the back of my brake pedal. Replaced the light sensor bumper with a 1/4-20x3/4 so you can imagine it was an awkward angle and having the right length was trial and error for getting it done.
They are just extensions, nothing extra fancy about them. If you can do with the quality of (when they were good quality) CM, Kobalt, GW, etc these will serve you just fine. The knurling is very useful also.

I've never had Snap-On money, so my old tool collection was a hodgepodge of random cheap tools. By far, I liked the Tekton tools in the bunch for price/quality, so when I lost all my tools, I just placed a big order with Tekton to replace them all. In the process, I picked up 1/4" and 3/8" extensions in chrome and 1/2" impact extensions, three lengths each.
My professional, in-depth, scientific review is: They're extensions. When used between a ratchet and socket, the socket is definitely further away from the ratchet, so job one done right there. I haven't broken one yet, even hitting the longest chrome 1/4" extension with an impact driver.
Alright, smartassery aside, I'm curious: what, aside from being less fragile, would make one extension better than another? They seem like pretty featureless sticks of metal to me, and I've never cared what brand is in the drawer. I'm picky about ratchets and spanners and screwdrivers--things you hold in your hand--but not extensions.

I have and use them. Compared to my Snap-on extensions, they flex a bit more but works well for the price.

Socket retention, having cheap ones that the sockets fall/come off easily gets to be a pain, and rigidness or less twist under heavy load. I actually have one that has a twist in it.........................

Bowing under load, detent balls falling out, thickness of the extension itself, knurled areas if applicable, and of course - how often they break.
It's like anything else. My fat William's usa extensions are fine most of the time, until they're not and I use the koken or snapon to get past something. Not saying you need snap on everything, my home extensions are tekton, gearwnrech, and yard sale craftsman. But at work, where it counts, there's reason to buy the fancy stuff.

I picked up a 3/8s set a few months ago and i like them. Nicest Extensions i have. I have a few that came with sets or just ended up with.
I have their 3/8" chrome set, and they got a good workout recently when I went shoulders-deep in the engine bay of my oldest's car. They worked well - good hold on the socket, the knurling is nice and I didn't notice any flex (though to be honest, I've never noticed any extension flex).

I ordered a set this summer. They are ok, but nothing special. Better than the random imports they replaced, about the same as my thirty or forty year old Craftsman and SK, not as nice as my SnapOn or Williams.
Good bang for the buck.

i bought the long 1/4, 3/8, and 1/2" sets a few years ago and they've been trouble free. i've used them with impacts and ratchets, again trouble free. haven't warped, twisted, or failed in any way. 10 out of 10 would buy again. i'm a home gamer, but i've given them plenty of use, several transmissions, rebuilding my truck, loaning them out to pro friends.

the 2 posts above re: flex are good reminders - if you use one with a torque wrench that matters
I have to inquire about this...you are saying that the use of an extension affects the value applied by a click wrench?
I'm not sure how that's possible in a near-static moment balance between the fastener and the clicker...but would like to learn.

I have to inquire about this as well. If we agree that the extension is made of "steel" then it all has the same Young's Modulus 30 x 10^6 psi for elastic deformation, no matter what type of exotic steel or heat treatment is used.
If the geometry is different in the driveshaft then this will definitely affect rotary compliance....but that would suggest that the SO has a larger OD in the shaft...

The fastener rotation stalls while the extension is torsionally loading and rotation of fastener will likely be less for same torque setting,
it bigger issue on digital angle torque ...
A lot of the extensions with better torsional stability are actually smaller diameter .I have to inquire about this as well.

Difference can be quite dramatic between brands, even in the lower cost spectrum torsional rigidty varies .

I would suggest looking at the Wera extensions. They have a really nice locking mechanism which keeps sockets from coming off, along with knurling and a sleeve. They are about as feature rich as I can imagine an extension being and it's all well done. I've looked at snap on and matco locking extensions and in comparison I'm not a big fan of their mechanism. Not nearly as nice to use.

they are fine....on par with similar tools in the same price range
GW, Husky, Kobalt etc.

I mentioned i got the 3/8s set and they are the nicest i have had. For 1/2in i have some craftsman and performance tool and a no name or 2. In 1/4in i have some husky and no name and i have an older snap-on 3/8 that im betting is from the 70s and had some rust and I still think the tekton are the nicest i have used. The only issue i ever had with an extension is rust in the ball or the no name ones breaking. I have never noticed flex but i never really paid attention to that ether

It's ONLY an issue with angle torque...with regular ol' torque settings, doesn't matter how much the extension twists as long as you can get to your spec, in the end the torque is applied to the fastener at the correct value. Only a problem if the extension twists so much that you lose clearance to turn the wrench or it breaks.
not always the case as if your regular torque setting falls a little after an extension flex point it will effect actual final rotation of the fastener, smooth movement without stall gives most accurate result, a long extension with lot of torsional movement slows or causes momentary stall of fastener which can alter actual rotation degrees of fastener for a given torque setting to some extent .It's ONLY an issue with angle torque...with regular ol' torque settings, doesn't matter how much the extension twists as long as you can get to your spec, in the end the torque is applied to the fastener at the correct value.

I think Snap On is actually slightly thinner than old Craftsman but turns up larger at the stress points near male end may be different (fatter) on the longer extensions
the Modulus for elastic deformation (twisting like a torsion spring under torque) is that Modulus really the same for all kinds of steel? Say Snap On's or KoKen's secret formula alloyed and treated steels vs. Harbor Freight's Chinese Special Bargain?

You think the torsion isn't going to be smoother than you just applying torque by hand? Unless you're building a nuclear reactor or some other precision thing, the infinitesimally small difference the extension makes will have no bearing at all on the torque applied.

Yes. Torsion is the same principal as bending - steel is steel. Torsional deflection is determined by the minor diameter. Not alloy or heat treatment. But if you spent 10x on Snap On vs Tekton extension you have to try to justify it somehow...
Modulus of rigidity is the property for torsion

I have some of the Tekton extensions in 3/8" was flipping them over on my tool table and can say they do have a tight positive fit on a socket, knurling is nice too.
I also have the HF WOBBLE set (very similar looking with the knurled grip) and I kind of feel you get the best of both with those. Cheap enough too with a 20% off coupon.

Also have to say both sets IMHO are superior to ALL the old Craftsman stuff I have for snug fitment on a socket
