I tend to order SEOH and Laboy most often for a majority of my experiments and products. Laboy isn't what you have probably come expect from a Chinese manufacturer. If you need glassware that just looks and feels like awesome quality--the answer is Laboy. I love Laboy for their quality. When I need something that I expect to break like beakers I tend to get SEOH (their prices are excellent), but when I get something with the expectation of it lasting a lot of abuse then Laboy is absolutely the way to go. It's worth it to spend a little more on some things this flask is definitely one of those items.
