Cons: hard to clean
Recommended? Yes

Comments: i got this with my kit, i love it. after i got this I have been secondary fermenting my brew to make a cleaner better beer.

Price: $45.00
Pros: Glass is about as sanitary as you can get. You can watch fermentation.
Cons: Glass is dangerous. Period.
Recommended? Yes

Comments: I still prefer glass over better bottles. I'd have several conicals rather than carboys, if that was a practical solution and an unlimited budget. It's not.

Price: $30.00
Pros: Clear so you can see your wort
Cons: It's glass and 6.5 gallons is not enough head space on a 5 gallon batch to avoid blow off.
Recommended? Yes

Comments: See above.

Price: $40.00
Pros: Easy to see any unclean spots. Cheaper than a conical. No worries of leeching chemicals.
Cons: Fragile, DON"T DROP! Harder to clean.
Recommended? Yes

Comments: I own four 6.5 glass carboys. I like using them because I can see what going on in my fermenter. I also like that they don't absorb or emit any chemicals. They can be a pain to clean but because they are clear you can see the spots you missed. Because they are glass, I use a milk crate to tote them around for safety. I've been fortunate to only have one break and spill my beer. It was because I used a siphon devise made of copper and it tapped the glass as I was getting the beer up the tube.

Price: $40.00
Pros: Glass, easy to clean and sanitize.
Cons: Breakable.
Recommended? Yes

Comments: It's a glass carboy. It's good stuff. Using it for primary fermentation.

Price: $40.00

Price: $35.00
Pros: Clear, easy to clean
Cons: Fragile
Recommended? Yes

Comments: I have two of these, they function great, and are easy to clean and fairly easy to carry with a neck handle.

Price: $35.00
Pros: visibility, no staining
Cons: harder to clean than a bucket, but not so bad
Recommended? Yes

Comments: Get a carboy brush! I always find that cleaning a carboy immediately after racking is the best time to clean it as no crud is caked onto glass. Then all that is required is a sanitizer soak just prior to next brew session

Price: $30.00
Pros: easy to clean. easy to use. if you want a glass carboy. definitely go with this 6.5 gallon
Cons: none that i can think of
Recommended? Yes

Comments: Other people seem to complain that its too heavy but i don't think it is. I can handle it fine. it cleans easy and it works like a carboy should. There is no need for a blowoff tube as there is plenty of room for the krausen in this carboy.

Price: $30.00
Pros: Allows for good headspace on 5 gallon batches.
Cons: Narrow neck makes it a little tougher to clean.

Price: $20.00
Pros: Got a great price from my buddy who works in the local brew shop/
Cons: glass. Always prefer stainless

Price: $1.00
Pros: Good Secondary
Cons: None
Recommended? Yes

Comments: A necessary upgrade for any home brewer. I got mine from my dad when he use to make home made wine.

Price: $20.00
Pros: Found six of these from a brewer selling off his equipment, all for hundred-dollars. Woot woot go Craigslist
Cons: I didn't have to spend $45 on each of them
Recommended? Yes

Comments: Always be looking and planning

Price: $60.00
Pros: I use this one as the primary for my 5 gal batches. Opposed to plastic bucket primaries, with this carboy I can see my beer. It's super easy to clean and sanitize. I can see my beer. It doesn't stain. Cleaning with a brush doesn't scar the surface, leaving it rough. Also, I can see my beer.
Cons: If proper care is not taken, light can definitely ruin the flavor of the beer. I ferment in a closet, so this is not much of an issue for me. Glass is heavier than plastic alternatives. I have huge muscles, so this is also not an issue for me.
Recommended? Yes

Comments: Glass is a more expensive option, but I feel that it's well worth it.

Price: $5.00
Pros: good head space easy to clean easy to add blowoff tube
Cons: heavy ass glass
Recommended? Yes

Comments: I'm moving to all BB eventually, or once I've broken all my glass carboys, but easy to clean and jam in a standard b/o tube.

Price: $45.00
Pros: Well it's glass and it is easy to sanitize and does not give off any bad chemicals(unless it is cheap glass). The only better product would be a stainless cone fermenter.
Cons: difficult to access product. HEAVY!(Get a strap)
Recommended? Yes

Comments: I love my car boys, I just look forward to the day I can afford a cone fermenter
