works as expected

Does what it is supposed to
Works best if you have a drill bit with a hex end and the same size.

Successful! 2-1/2" dia X 12" long hole in hardwood cat post/kid post (with a modification)
Four stars because does not work without a modification. I was worried when I read the other bad reviews, but I had no other alternative for the task at hand. So I bought this extender, and rather than risk the drill bit spinning around in the extender because the set screws would probably not secure the bit under the punishing drilling I was about to do, I decided to modify my bit. I flattened the 2-1/4" Forstner bit shank in the two spots the set screws would touch in the hopes that so doing would keep it secure. It worked! I drilled a hardwood, 3-1/2" log, 12" down the center - that's along/with the grain - not across the grain. The first 3 to 4 inches I did without the extender, but I had to use the extender to make the turn/follow the bend, and that alone took a half hour to go the last 8-9" after the bend. Flattening the shank for the set screws like I did, held just fine. P.s. The drill bit metal was so hard, a hand mill file did nothing to it, so I got out the Dremel with a chainsaw sharpening grinder attachment, and that did the job handily (and the bit still works just fine in a chuck). See the photos...

poor sizing
The female side of the chuck doesn’t actually fit a 3/8th inch driver. That’s a huge oversight or mis measurement.

Really crisp drill, 10/10. Not much to complain, maybe got a longer model in the future?
Drilled throu fresh wood, spruce, with knots and burls, still did an amazing job, cant get much better then this. When it comes to wood-drill.s

Good if you have patience and no how
The length is good but the set screws are poorly designed. I replaced the screws with longer set screws for smaller diameter attachments

Great

Does not accept a 1/2" shank
Great quality except it does not accept a 1/2" shank. The hole is 1/2", this causes an interference fit. I had to take .003 out of the bore to be able to accept a half inch shank drill bit

Century Came Through!
One of the two Allen key bit tighteners was not manufactured correctly. It's not deep enough for the Allen key to tighten correctly. As a result the unit must be handled with care as the bit will most likely come loose. Tried to find a replacement screw tightener, but so far no luck. I would ask for a replacement tightener, but I can't find how to contact the company. *** UPDATE: I was able to contact Century Tools directly and requested they send me a Allen key bolt tightener. They did one better, they sent me a whole new unit and it works great. I will buy more items from Century in the future.

Ok extension
I got a deal on the extension. It was the right size to extend my large size, +1 1/8" , hole saws. Built sturdy with perfectly in drill. Get it to the job site and pull it out to use it and no set screws. Completely useless to me for the whole day. Insulators got in front of us and cost me 3 extra days labour's.

Not as advertised.
Does not run true (wobbles). Also not bored properly to accept ⅜" hex shank. The auger with ⅜" hex shank that I also bought on Amazon, does not fit into this, although the auger DOES fit into the drill's ⅜" chuck. I don't recommend this extension and won't buy it again.

Not bored properly
Purchased three and one of the 12" the extension was not bored properly, did not bother sending it back, if needed will bring to a machine shop and have it bored properly.

Does NOT accept 3/8 in shanks
My 3/8in drill bit did not fit in the extension. Worst of all, I didn't get around to trying it until after the return period, so now I'm stuck with a useless metal rod...
