Thicker glass than anticipated
I use this flask to make > 2 liter yeast starters for beer brewing. It works as intended. I was pleasantly surprised that the glass is relatively thick compared to other Erlenmeyer flask I have used.

Works as intended. It did have some small scratches and scuffs but It doesn't effect the product.

Great quality!
Very high quality flask! Much thicker glass than most 5000ml flasks I have used and broke!! I also purchased 2 of the 3000ml flasks from MoreBeer and they are the same high quality thick units!

Awsome
Got it quick! Really needed a bigger flask for bigger brews. Read a lot about people saying the stir bar wouldn't stay, so I immediately filled it with water and I have no problems with mine. Great looking flask and I'll have a starter in it this weekend!

Problem
Well built, nice flask but one major issue with the one I received: the magnetic stir bar will not, even at low revs, hold in the center. I use a 2" bar in a flask this size as the 1" does not have enough "juice" and it keeps getting thrown to the side. I tried several different bars and even the smaller one to see if I could get it to hold but to no avail. I put 3000 ml of water in the flask so I could hopefully see the problem and I think the bottom is crowned or convex so the magnet tends to drift to the side, thus causing the problem. Oh well, back to shopping for another flask.

Concave Bottom renders useless.
The bottom of the flask is concave and not flat. This prevents a stir bar from staying put, essentially getting thrown to the edges of the flask at all but the lowest speeds. Therefore it is essentially useless for its intended purpose.

Glad I got a 5L over another 2L
I can still make a 2L starter in this flask, but when I need a bigger starter for a larger batch or for a lager, I'm glad I can make it in one flask.

A must have for big beers or 10 gallon batches
The easiest and safest way to make a starter is with borosilicate glass. I have 2 of these 5L flasks because 1 just wasn't enough.
