Great!  It's 1/2" though - make sure you need 1/2" versus 3/8" mic stand

Very nice item, but could be 1/16th to 1/8th of an inch bigger in diameter so it will fit snugly into a 2" hole, especially on a vertical panel.
It would be fine on a horizontal table or desk top, but will fall out of the holes I made in the side of a road case with a 2" hole saw.
Not a huge deal, I can apply a bit of adhesive to get it to stay in place, but saying it is a 2" grommet, it should fit snug enough to not fall out of a 2" hole. Still very happy with this purchase and will be getting more soon.

This is 1/4 inch. NOT 1.25 inch. Be careful not to be mislead by the title.

High quality product.  It looks and works great.  I have an EverPure filter system with a 1/4" plastic flexible pipe.  The Zuhne Faucet does not support 1/4" pipes, so I went to a plumbing shop and bought a 3/8" to 1/4" adapter for $5.  Be sure to bring the installation manual with you so that they can confirm the adapter size.  Many plumbers won't have this on hand, so be sure to get the adapter before your plumber comes out.

Incorrect specs included on the details page.....works great, but it's about 2-3 inches longer than described

Just what I needed for my project! Also, the dimensions are almost EXACT! So you can count on the specs down to the mm. I needed this to fit exactly and it did.

Just keep in mind that the screws are small, so a normal screwdriver may not fit well to tighten the wires down.

Looks great. Double check the size. I think it is 2 inch wider than what was specified. It worked out okay for us though.

Works great!  Could be a tad taller and softer, but nearly perfect.

Great lead/easy to use.  I wish I had gotten the 1/2" because this one is rather small.  My fault and has nothing to do with the quality which is great.

I bought the 1 1/4 by mistake, but after useing a little strip of rubber it works great and for a very low price.

Arrived on time and as described.  Was already calibrated.  Works great on 1/2" and starts to get tough when doing 3/4" connections, but still works great!  Would definitely recommend it.

Great product - very nice and works well.

Word of advice - read the measurement specifications carefully!  I didn't catch that my door hole wasn't big enough until the deadbolt wouldn't fit.  My mistake, but just be aware that you may need to get some drill hole saws that cut through metal/wood.

Was a pain in the butt to cut it to the right size.  Two trips to Lowes and Home Depot.

I had to return it.  Mine has 1/2" to 3/4" adapter built in, which I'm having a hard time finding.

it's a little big but works great I've had mine for 1 1/2 .

This is a great stand to mount your Mic/Light/Extendo-Arm device to the wall rather than your desk.

HOWEVER, it is probably a SMIDGEN too small to be classified as a 1/2" opening. It's more of a 15/32" of an inch opening.  A 1/2" drill bit will not fit directly down the opening.

If the opening was proper and standard for every other extension/boom device sold on Amazon, they would sell a TON of these.

Great! Though mine is a different brand the 2 1/2 inch outside diameter fit perfectly.

this worked better than I expected, however it was about a 1/2 inch short of meeting at the bottom. I just cut a piece of the old one and "patched" it in.
