Works as it should
As long as you purge it with a few seconds of air after you take it out of the wort (I also rinse with water) it seems to work just as it should. I've made quite a few batches with it. I also store it in isopropyl alcohol between batches (keeps anything from getting in it, or growing in it).To the folks that had it plug up, boil it in clean water for a bit -that should help loosen up whatever plugged it (likely sugar). Purge it after you use it!

Works like it's supposed to
I got this carb stone with the oxygenation kit. It works perfectly. As other reviews state, I do NOT handle it, boil it before use, and push some air through it before AND after use. Thirteen batches and no issues.

Works fine if you keep it clean
I've used mine in 10+ batches wo/ a problem. But (a) I boil it for 10 minutes before use and (b) I always blow it out when I'm done aerating. I just keep it in its original plastic bag between uses. After about 10 batches, the flow isn't as good, so I replace as needed. For those having issues, recommend a good boil before and a good blowout after use.

Works well but watch the pressure
The half micron stone (actually stainless steel) works great, producing a very fine froth of bubbles at low flow rates. It has really cut down on my oxygen use.Advice: Use a clamp to hold it onto your tubing. I use a medical flow regulator and if the flow is turned up too high it generates a good deal of back pressure in the line causing the stone to pop off in your wort and you have to fish it out or wait for the batch to finish fermenting to get your stone back (learned that the hard way). Purge the stone with O2 after use to keep the pores clear but if the stone pops off and hits a concrete floor it can break (done that).

Does what it's supposed to do.
No complaints. The stone helped oxygenate my beer.

Used for multiple batches, no problems
I keep the stone clean, sanitize it with StarSan, wash it with PBW, rinse with water, and I ALWAYS run air through it from an air pump until it is dry whenever it has been exposed to ANY liquid. I am probably up to 10 batches with it and it works as well as it did when I first got it.

Have used this for the past two years.....
Works great and doesn't plug up if you rinse it after use. I store mine in rubbing alcohol and then use gloves when rinsing prior to use. Not long after purchasing, the stone started popping off the metal barb. I was still able to use it until this last batch where the air pushed it off the barb and it had to sit in my primary through the fermentation. Then I forgot about it and it got eaten by my garbage disposal when I dumped the trube. I just ordered my second one, so hopefully the stone stays on the metal barb a little longer. Overall I would recommend this.

Marginal
First stone didn't work at all, was advised that they get plugged up pretty easily. Second (replacement) stone worked once, then was stored properly for two weeks, and not a single bubble would it emit when used again. Human hands NEVER touched the surface of the stone. I believe the idea is valid, but this particular product seems to be not user-friendly at all.

Did not work at all
I got this stone in the aeration kit. Has not worked at all. Not a single bubble. Never touched by human hands. Have tried boiling it and I put high pressure air through it to clean out the pores, with no luck. Might as well throw the thing away.
