Solid usable Glass Carboy, BUT Cracked....

Only gave 4 stars because the item came cracked, but don't believe it was any fault of amazon.  The carboy is pre-packaged and the damage seemed to not have been caused by shipping.

Received this product promptly.  Looks like an excellent item for the price $25.00 plus free shipping (Prime member).  I unpackaged it an it looked great however, when I turned it upside down to inspect the bottom there was a crack along the bottom of the bottle.  I can use this for fermentation it would be a ticking bomb, beside the crack went all the way through.  Looks like it happened at the warehouse, someone set it down with to much force or dropped it down.  also the orignal packed box (came in a inner orignal box and outter protective box) was weak and depressed in, the bubble was that thin layer stuff that you would normally wrap electronics parts with.  Over all I think the product is a a good buy, I'm waiting on the one amazon sent me as a replacement.  I like it so much that I went ahead and ordered another on to have two of them.

This was a great container - kind of difficult to clean unless you have the luxury of a dishwasher. However, the glass just started cracking in my fridge this morning and I had to throw it out.

I bought this since it seems to be the only hot drink container not containing any plastic.  It was working fine but one day cracked while pouring in hot water.  A bit disappointed in the quality/durability of the glass

I bought the 1L version a little while ago and the coffee itself was fantastic.  It was easy to use and the coffee came out perfectly.  It was easy enough to prepare when I got home from work and have cold brew coffee ready for me by morning the next day.  Simple enough to do that I could make a few batches in a week if I was going through it quickly.  The con is that unfortunately the glass is very thin as advertised in other reviews that I had seen.  The cold brew coffee maker cracked at my third use.  It's a shame because the product itself is great other than this flaw.

I purchased this coffee press in conjunction with the Hario MSS-1B Mini Mill Slim Coffee Grinder.

The press fits nicely into the carafe and pushes down very easy.  The press and carafe also clean up with minimal fuss.

Overall, the product seems to be well made and a great value for the price.

Updated:  07/29/2013 - glass cracked on bottom of carafe, item was not dropped or handled roughly, plastic nut that holds inner ring of plounger to top of lid broke as well.

This is not an expensive item so I guess I got what I paid for.

I'm starting with one star but hopefully it will be changed to 5 if Hamilton Beach sends a good carafe.  First brew and it cracked.  Giving a couple days to see if they send a replacement.  Will update when I can use it.  Anyone else have the carafe break on first brew or is this a fluke?

The bottom part came with crack on it but i really needed to start the yeast for a homebrew beer i was making so i could not return it on time.

The glass bottle is nice. The cap for the bottle cracked all the way around the first time I screwed it on. I didn't think I even tightened it to hard. It's usable but cracked and damaged. Be wary of the cap.

I got glass weights to use. When I pulled the first one out at the end of the fermentation period the weight barely tapped the bottle neck area. It broke. Eggshell thin. The price isn't right if it's a one use item.

I really enjoyed it the handful times I used it. Unfortunately, the glass was very thin and brittle that it shattered after a few times. It wasn't due to a drop or hitting it against something. I guess the water was too hot?

The filter is great though. I still use it on top of cups.

UPDATE: I have been contacted by Coffee Gator and offered a replacement. For the fast customer service response, I have added another star to the review. I will update again when I have received the replacement and put it through its paces.

Fairly heavy low grade glass, inclusions and such but OK for its purpose. (I got it to brew kombucha and I think it will do just fine. There is a good flange around the top, perfect for holding a cloth cover with a rubber band.) But, the plastic spigot leaks badly from around the valve handle and is made really cheap and nasty, the chrome flash finish is even flaking off the new part. Disgusting. Useless. I ordered a new spigot for it, a:

The drilled hole in the glass is 0.71 inch diameter and there is a nice fat vinyl grommet with a 5/8 hole, 5/8 deep, 0.2 thick lip inside and outside. Right, vinyl, nasty but probably won't kill me. Maybe the replacement tap will have better washers.

I haven't yet tried the replacement carafe, the spout was shattered upon arrival. Like many other reviewers, my glass carafe broke during cleaning. UPS pick up was smooth.

UPDATE:  I have used the replacement bottle with no problems (see comments).  I'm impressed with the customer service and the bottle.  While I haven't exactly attempted to break it, it's seen some use and done fine.

Original review:

Today, I used my new water bottle for the first time.  I loaded it up with pineapple, ice, and water, and I was pleased. The infuser worked, and the bottle has several nice details that keep its integrity, like a soft plastic piece that goes down into the water spout for a tight seal.

I honestly don't know if the item is flimsy or if I'm just unusually unlucky/clumsy, but I tripped and dropped the bottle this morning, and the button broke.  This water bottle has a locking mechanism that requires a button press to open  My button broke off.  It wasn't a particularly hard fall, but I nicked it in *just* the wrong spot, apparently.

I'm not going to send it back for this, but I am pretty bummed about it.  It'll work around the house, but I can't really carry it out since I can't open it any longer.

I actually really like this product.  I'm the only coffee drinker in our family so my coffee supplies have to go in the pantry - read, no coffee maker.  This gave me the option of making a cup to go or to pour into a regular mug to drink at the breakfast table.  My wife bought this for Christmas - just over 10 weeks ago - and pouring the hot water in this morning I heard the inner liner crack.  After I cleaned the mug, I could see a crack starting at the bottom of the inner liner and running about half way up the side.  Sadness.  $27 for 10 weeks is $2.70 per week...too much in my opinion.

That said, I like it enough that I think I'll give it another shot...probably stainless this time.

It filters water and it tastes fine, but mine arrived broken - the handle had snapped off. I realize this may not be a product deficiency, but rather a shipping one. Still, I would have hoped a hard plastic handle would have been a bit more durable then that. Haven't bothered to return it - I need fresh water in my apartment and I don't trust the tap. The pitcher still works, even with the handle snapped off, so that's how I've been using it. It filters water quickly and with no evidence of carbon filtering into the water, all positives.

Purchased 2 refrigerator bottles which have served me well. However, one of them has a valve that drips after use and the other developed a small crack at the back.
