Excellent product! Excellent customer service!!
This flask is a great bargain for someone looking for a big flask for lager starters.
This flask is comically large. I had to move shelf positions on the rack where my stir plate is located in order to fit it. I did not see any glass issues with it though. For its relatively cheap price, it's great for making large starters.
I received the flask fairly quickly. Upon inspection I noticed the glass quality around the rim had small bubbles in it. As the flask was only $40.00 I did not see this as a problem. I have used it many times since with happy results.
