The ad clearly shows a Shuniu flask. I have and love my Shuniu flask, but what arrived was decidedly not that. :/This no-name flask looks mass produced. The bottom is just a bit uneven with easily perceptible flaws, and the mouth was more so. To add insult to injury, the stoppers reek of vulcanized rubber (think tire store), and there is no way I'd want those anywhere near something I want to actually drink.Trust me, and stay away. SMH ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great size, but slight deficiency *by E***. on Reviewed in the United States on October 26, 2016* This thing is huge, and will easily hold 5+ liters of starter wort. It arrived extremely well packaged, wrapped in both foam and bubble wrap, then kept secure in the box with wadded kraft paper. My only complaint so far is a slightly domed bottom (-1 star.) Concerned, I put 5 liters of water in it and tested it with both a 1.5"  Bel-Art F37110-0112 Spinbar Teflon Octagon Magnetic Stirring Bar; 38.1 x 8mm, White  and 2" Bel-Art F37110-0002 Spinbar Teflon Octagon Magnetic Stirring Bar; 50.8 x 8mm, White  ribbed stir bar. I got a good vortex, and could crank both up to max speed and not throw the bar, so at least I know it'll work with my homemade stir plate. I'll wait until I make my next big starter to see how well it performs with hot/cold wort as well as how accurate the graduated markings are, and will report back on what I find. Right now, I'm happy with it and the really great price. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It is big. *by Z***G on Reviewed in the United States on July 14, 2017* It is big. The one I got has a tiny bubble at the base, but it does not seem to be an issue as I was able to bring water to a boil. The walls are thick and robust.The black stopper has a weird smell so I got a size 12 white (ivory?) stopper which works a lot better. Much softer than the black one as well.I am very happy with this purchase, I may buy another. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/10512907-5000-ml-fermenter-flask-with-stopper-and-airlock](https://www.desertcart.pl/products/10512907-5000-ml-fermenter-flask-with-stopper-and-airlock) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-02*
