These are indeed a necessary item to have plenty of stock on hand when topping off a carboy with wine, ready to be aged...and, of course you have likely have more airspace leftover than wine, to fill up that carboy!

I will likely get more because the weight of these marbles do not translate well to thinking in volume when needing to fillup all the other 3, 4, & 5 gallon carboys.

Great price and pleased with the quality of the product.

I apparently thought 3lbs was more than it is. Its exactly as shown but its a small bag so it wasnt enough for what i needed and ill have to get more. But ill look for cheaper because im not paying $25 again.

Haven't spilled a drop yet-very good

Put away the potato masher and keep your elbow out of the must...this tool is a must!

Lee's stirrer works great. Better than the whip it in my opinion. Bought one that got damaged in shipping and they quickly sent me another one no hassle. Great customer service thank you

Fantastic price but its so heavy. I am not using it rather I am still using my light plastic beer stirring tool to punch down the grapes. It is just easier and less surface area to cling onto sanitizer and easier to clean. However when the grapes are first thawed the heavy tool will be useful.

I wanted something that could be used would both wide-mouth carboys and narrow glass one-gallon jugs. This is perfect even fits in my supply box.

Sometimes I have a need for topping off a wine when I don't have a good alternative topping wine or the volume needed is such that my available topping options are not optimal choices. These marbles are a great alternative in those circumstance and they clean up easily and are easy to sanitize and store for future use. Overall this is a good tool to have in one's home winemaking toolbox.

Works great. Screw attachment was fine and wand didn’t move.

Worked exceptionally well. Well worth the investment.

Does it’s job without sucking on the bottom!

Sturdy and quick to degass my wine after failure to degass properly with wine whip. I still had co2 after 9 months of aging. This seems to do the trick. Now I am ready to reuse my carboys for this year's batch.

Bought these to top up my 3 gallon carboy for a batch of wine and they did indeed top it up.

Works well but there are a lot of crevices for bacteria to get stuck in…

Good for topping up carboy. Works as expected.

Durable and I just throw it into the dishwasher to clean and sanitize

This unit would be fine if the description was accurate. However the straight portion is shorter than described. Not terribly so but enough to be unable to reach the bottom of my barrels.

When I started making wine it was a hazzle trying to figure out the different many components needed to ferment a high quality wine. The GoFormentor made it easy to understand the whole process and easy to control the critical aspects of wine making which are cap management reduction of exposure to unwanted bacteria from the environment and a temperature control while fermenting. Overall great product with great support from the manufacturer.

Works as advertised. Simple to use in our wine barrels. Very satisfied.

I just received it but haven't used it. Can say that it is very sturdily constructed and looks like it will work amazing.

Works great for mixing in back sweetner into my Ciders & Wines.

screw at bottom seems sufficient in length for our uses not sure it More Beer put a longer one on

Worked great! I used 9 lbs. to top up my 5 gallon carboy of black raspberry wine. Just about a hand full had small cracks and bubbles close to the surface. I picked through and put them around one of my plants. Didn't want any small pieces to end up in my wine. I will be buying more for my next batch. I'll just pick through them.

Excellent quality. Well made and easy to clean. Used mainly for smaller batches of whole grape must in a 15.9 gallon fermenter. Definitely recommend!

Fine tool but i did change the screw to a longer one and it works great

It does the job for sure! Just can’t hang it up...don’t forget to have your drill charged and ready hahahahaha

Bought to maintain a good head pace in carboy

The marbles are what I needed to raise the wine level and remove the air

Excellent heavy duty product should work well this harvest season!

I have had this exact model for over five years absolutely love it! Rugged easy to clean/sanitize. Recommended.

I'm using these for fermenting vegetables. They are working well.

Makes punching grapes so easy !
