Lässt sich super befüllen. Große Öffnung. Das Essen schmeckt sogar direkt aus dem Topf! Reinigung des Topfes sehr einfach. Reinigung des Deckels nicht ganz so einfach, aber wenn man den Dichtungsgummi zum Reinigen vorsichtig abzieht und mit einer kleinen Bürste mit Spülmittel arbeitet - Null Problemo! Hält superdicht und wird außen nicht warm. Ich bin begeistert! Endlich eine Alternative zur verhassten Mikrowelle. Edelstahl, kein Aluminium! Also mir fällt nichts negatives ein. Ich kann das Produkt bedingungslos weiterempfehlen.Ich muss eine Zusatz-Info anfügen: ich bin ja wie gesagt eigentlich begeistert von diesem Warmhaltebehälter. Aber letzte Woche passierte es tatsächlich, dass ich den Behälter ca. 6 Stunden nach dem Befüllen nicht mehr aufbekam. Also Totalausfall. Haben alles probiert. Am Ende war das Gewinde schief und der Deckel hatte sich so sehr verhakt, dass wir den Behälter leider samt Inhalt (Blumenkohl-Suppe) wegschmeißen musste. Nach 4 Wochen in den Müll. Ich war sehr enttäuscht und bin mir nicht sicher, was genau falsch gelaufen war. Vielleicht zu heiß befüllt? Vielleicht zu voll befüllt, dadurch beim Abkühlen zu hohes Vakuum? Vielleicht Dichtungsring verrutscht und dadurch etwas schräg zugedreht? Ich kann nur anraten, nicht zu voll machen und nicht 200% zudrehen! Neuer Versuch mit neuem Behälter. Da ich inzwischen 5 Stück gekauft habe und zu sämtlichen Geburtstagen gerade verschenke, hätte mich eine kostenlose Ersatzlieferung vom Lieferant gefreut. :-) ### ⭐⭐⭐⭐⭐ Holds heat very well and no leakage. *by H***Y on Reviewed in the United Kingdom on November 14, 2018* Excellent 1tr flask. Holds the heat very well. In the morning, I pre-heated the flask with boiled water. Filled with hot soup. And it stayed boiling hot till the afternoon. Approx 7hrs. I would say the 1ltr is your best bet for hot liquid keeping its heat, rather than the smaller ones. It seems a lot but I found it to be the perfect size for lunch and a snack later (I work from 1030-2130). Light weight and love the black sandblasted finish. This will last a lifetime. The screw on lid is designed to have a loose fit to allow the steam to escape gradually as you unscrew and not to release all at once, possibly causing a mess. The lid tightens up well and did not leak whilst in my ruck sack. ### ⭐ Misleading discreption. *by V***N on Reviewed in the United Kingdom on May 19, 2022* The description on Amazon says 24hours COLD... Is this a joke? When I received the item, on the packaging the description was 8hours cold. Only 12 hours difference :P. The truth is that it hardly keeps something cold for 8 hours. I placed the flask in the freezer overnight and at 6:00 in the morning it was super chilled and I added yoghurt. By 14:00 it was less cold than the refrigerated yoghurt. I am not sure if I will keep the flask, as I purchased it to keep food cold and not warm. Very disappointing. --- ## 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.vn/products/168210062-pioneer-vacuum-insulated-leakproof-soup-food-flask-8-hours-hot](https://www.desertcart.vn/products/168210062-pioneer-vacuum-insulated-leakproof-soup-food-flask-8-hours-hot) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-10*
