These flasks are garbage!
I've had two of these flasks and both cracked under normal usage. After the first one, I thought I'g give the brand another try. Knowing how fragile the first one was, I was extra gentle with this one. After only 3 staters, I noticed slight amount of liquid on my stir plate. Upon inspection, I discovered a crack on the bottom of the flask.
I could have bought a lot of yeast for the $150+ I spent on these. They're garbage- Stay away!

Great Service, Bad Flask
After making over 100 starters in my trusty 5 L flask from a competitor, a crack formed so it was time for an upgrade. First use of the Northern Brewer 5 L flask, using a separate pan to boil and a funnel to place hot wort in flask. After placing the flask in cool water without ice and a crack formed. Northern Brewer was very prompt with their customer service and sent me another no questions asked. Second unit was not any better, as with the same procedure a crack formed. Again, customer service was nice enough to send me another unit with advice to change my procedure. The third unit I received has a noticeable bubble on the seam of the flask. The third unit is untested at this point. Just avoid this flask unless you plan on trying your luck for a decent unit. Regardless of what happens to the third flask I will not be purchasing another one. Two stars given for the customer service and standing behind the product. However this is a one star flask.

It's Huge!
It's big, get's the job done, and looks really impressive when your non-brewing buddies see it sitting on the Maelstrom in the background.

Not Pyrex, made in India, cracks
Buyer Beware. This is not pyrex and does not hold up to heating and cooling quickly. After making a starter for the first time, this flask was put into an ice bath and cracked. I thought the price was too good to be true and it was. Product is clearly a knockoff, made in India (labeled on flask) and does not hold up like Pyrex.

Expensive and Wobbly
Not entirely pleased with this purchase, this flask is priced significantly higher than the competition and the glass bottom is kind of wobbly

Great for large starters
I had some spill overs when trying to make large starters in the 2L flask so I bought this one. I would rate it 5 if the stir bar didn't stick a bit to the sides when starting the stir plate.

Awesome for high gravity or 10gallon brews
I'm new to brewing but this flask has been awesome so far. Safe to boil in on my little gas burner, my DIY stir plate with either 1" or 2" stir bar will get a strong steady vortex for 24hrs, what more needs to be side. Definitely worth having in your brew room if you do 5gal high grab beers and a must for 10gallon batches!

Gas vs electric stove
With a gas stove, camp stove or other gas sourced heat the flask will not break. They all have a grate between the heat source and the flask and are not "direct heat".An electric stove's heat is too direct and requires a buffer. Either make a "trivet" with a coat hanger bent into a star pattern (google) or even place a thick frying pan or sauce pan between the stove and the flask. I hope this helps.

Handle with Care, Fragile
These have a tendency to break, I was told that they sometimes contain flaws exacerbated by shipping. The first one I received broke just sitting in my ice bath after heating my starter in it, but I called and it wasn't a problem to replace. I won't be heating it on my stove or putting it in an ice bath to chill any longer. Recommend treating it like glass.

I thought these were supposed to be borosilicate, meaning they could handle being heated and chilled without exploding? Seems to be mine wasn't cause I have a pot of cold water with 5 liters of malt and a large crack in the glass
