Very high quality product. Easy to use to aerate your wort before pitching yeast. The o2 gives the yeast a head start

Works great and reasonably priced. Even comes with a filter. Oxygenate your wort!

Well made and perfect for a small bottle of O2.

Works great. Easy to use. I gave it 4 stars because there is no pressure gauge. No product for a beer kit has it yet but when they make it ill give them 5 .

Really love it Can’t go wrong here ... helps your yeast be healthier and eat more east

I prefer the systems that use the stainless rod instead of the black tubing but this one works fine. My fermentation and attenuation is more consistent and complete with the use of oxygen and a starter. I have not tried a side by side comparison for flavor but consistency I think is key in brewing.

This has made my beer much better. Easy to use and no more agitating a heavy fermentor.

The benefits of oxygen to yeast health are undeniable. Why not give your little buddies the best possible chance at making great beer? This set-up gets the job done well. The black hose between the air filter and the stone is pretty rigid and can be difficult to manipulate. A ss wand might be preferential, but that would up the cost.

No issues at all. Hooked it up to the tank and it seems to work great. Fermentation seemed better after doing so vs. the shake method. Worth the price in my opinion.

I use oxygen in my beer and couldn't be happier with the results. I could easily see the benefit by purchasing this product by how well the yeast took off. Stone cleans up easily boil it for 5 min. Highly recommended.

When brewing big batches you can't shake them so I put this in my brew kettle then pour in my fermenter.

No regrets here. It works great, no issues w/ cleaning. I've used on probably 15-20 batches and no problems yet!

Takes one minute to do what my aquarium pump does in 30 minutes. And fermentations are fast and furious. Local Ace Hardware sells O2 canisters for only $4!

Quicker fermentation with the addition of the proprer amount of oxygem in every brew. Worth every penny spent!

This is a no-brainer. Oxygenation is quick, easy, and loads your wort with plenty of O2. No more shaking, splashing, etc. As a bonus - you can push out air that might have contaminating organisms, so there's less chance of infection.The cost of the small O2 tanks spread out over your batches adds about $1.00 to the cost. The cost of this is a one-time investment. Well worth it for a better quality beer in less time and with less hassle.

Just remember you screw this thing on the oxygen bottle lefty tighty, righty loosey. Confused me for like half an hour.

This O2 system is made from high quality components and works flawlessly. The price is somewhat high, but the performance is so good that you probably will not mind.Side note: It is a pain to store as the black part of the wand and the O2 tank are both long and unwieldy.

Works perfectly, I use this with all my brews.

Great results, I feel the oxygen has made a big impact on fermentation.

Must better than living 5.5 gallons of wort in a carboy and shaking it.

Since adding this to my equipment inventory, I have noticed much better fermentation. The only thing that took me a little while to figure out is the backward threads when connecting the Oxygen tank.

A great product, though a bit hard to sanitize the black part that goes into your wort since it's not very flexible.

This worked great for a quick shot of O2. The only issue I had was needing to run to the store all the time to get new bottles of O2, which I went through pretty quick. I only got about 3-4 beers per bottle, using it for 1 minute/brew.

Very effective - However, I don't like the black tubing that connects to the aerator... it is too stiff. It is still partially curled up from being wrapped tight in shipping.

This product has improved my brewing amazingly. Physically, much easier to use than shaking a carboy by hand and the effect is so much better. May be the best addition to my brew system in years.

I've used this system for the past 9 years with consistent success. Easy to clean/sanitize and simple to use. It certainly makes a significant positive difference in the yeast growth phase, especially with big OG wort. The only issue I can say is the hose tends to curve around and upwards toward wort surface when in carboy/bucket which creates minor difficulty. Overall a great product.

I have had more vigorous fermentations and better tasting beer since I started oxygenating with this system. Works great with disposable tanks from one of the big box hardware stores.

These carboys from MoreBeer are simple, but the best available. They are much easier to clean than some of the other popular brand names. And, if you're easy on them, they will last a long time.

Best money spent. Had a issue with the filter broken during shipping. More beer sent me a new one.

Much faster fermentation starts than via shaking. Super simple and requires only a bottle of O2 from the hardware store. One small tank has lasted me about 5-6 5g batches.

This item has made oxygenation so much easier for me. No more shaking carboys or buckets, and no more pouring from kettle to fermenter over and over. My fermentations have been healthy and vigorous with individual smack packs, starters, dry yeast sprinkled, and re-hydrated dry yeast. They all seem to perform well after adequate oxygenation. I am very pleased with my purchase

Probably the biggest bang for the buck improvement I've made was getting one of these to use with the red welding O2 bottle for oxygenating the wort. Shorter lag times and less off flavors.

This has really helped the fermentation on my last couple of brews. I was having occasional problems with the yeast fermenting fully and found that using this to oxygenate the wort really has helped.
