I fill this with boiling water for all-day herbal tea hydration, pretty much every workday. I LOVE it. It keeps the water hot and is very tough. Please note, though, that replacent parts may not be available as Stanley advised me that this product has been discontinued. I don't know what will happen if the gasket wears out, or if/when I lose it. I can't find compatible ones anywhere.

Produto maravilhoso. Sou professor de Educação Física. E a Growker está comigo a todo momento.
Além deste produto tenho dois copos ( com e sem tampa) e já aproveitei as promoções de dia das mães e dos namorados e adquiri duas garrafas. As garrafas vieram com nomes gravados.
Ficaram lindas.
Minha próxima compra será da nova coleção da Stanley ( cafe)
Resumindo, recomendo muito a Stankey.

Well made product. If you pre-chill it seems to keep beverages cold for several hours when the growler is at room temperature. Seems to seal well and hold carbonation well for a couple of days. Seal disassembles for cleaning. Only issue I’ve experienced is that it seems to dribble a little when pouring but it’s a minor annoyance.

I have had a Growler for 5 years now. The one I have has been discontinued. The lid eventually broke off. The hinge on the lid became weak over time and extreme excessive use. I used the hell out of it. I was took it to work and filled it with water. It kept my water cold all day, which was a God send. Prior to owning my Growler, I would buy 1 Liter bottles of Aquafina and within an hour or so, it would be warm. Once I purchased the Growler, I never had to deal with warm water again. This thing was incredibly durable and alway reliable. I used it everyday, all day. Stanley is such a great company that they are replacing it, even though it's discontinued, with a better one, in my opinion. What a great company! I will always bring my business and recommend to everyone to bring their business to Stanley. Anything else would just be uncivilized.
