Product Customer Reviews
Excellent product. Go for it
Easy to operate the lid, the tea stays warm for a long time, so great satisfaction
The best thermos I've ever bought. It keeps things cold in the summer and warm in the winter beyond expectations. The cap is also durable.
Maintains temperature well
Useful water bottle to keep drinks cool, with a convenient spout to make my children drink. Top size and resistance.
Modern, functional, comfortable to use. Excellent parameters make the drink stay hot for a long time. The thermos does not slip out of your hand. It is easy to clean. I bought it for myself and as a gift for others. I recommend it.
I had previously purchased the product from the application, and within 3-4 months it rusted inside, and we exchanged it from the store. Normally, it is very pleased, its structure does not feel too heavy even when slightly filled. But now it started to seem like it was not keeping warm, and the circular connection piece on the bottom of the thermos fell off. The rate of keeping warm has decreased to very little. There is no store where I live, what should I do?
It has proven itself during several expeditions in sub-zero temperatures.
Great insulated bottle that keeps the cold well and can be used to keep warm in winter. Very practical
Bottle Cap lock has turned out loose after usage now. Overall great product.
Excellent, comfortable and keeps the heat and the cool well
It is not protecting hot water
I use it for both hot and cold drinks. The lid design of this model is also suitable for hanging it on my bag outdoors. I have dropped it many times but it has no problems.
hot water is still available at the end of a day
practical and easy to handle steel water bottle
Additional Product Information
Composition
Bottle/Body: 100.0% Stainless Steel ; Lid: 81.0% Polypropylene, 8.0% Silicone, 10.0% Polyamide, 1.0% Stainless Steel
How is heat insulation tested?
We’ve tested this flask in the lab according to Standard EN 12546-1, at an ambient temperature of 20°C while filled to capacity. The time it takes to drop from 95°C to 50°C (drinks temperature considered warm enough to drink) is 23 hours.
The secret of the insulated flask?
This insulated flask’s stainless steel double wall with vacuum blocks heat by conduction and convection. A thin layer of copper reduces thermal exchanges by radiation. A few tips to improve thermal insulation: fill your flask with warm water for 5 minutes, and then replace the water with your hot liquids, then close. The fuller the bottle, the better the heat retention.Warning: the flask is very insulating, the liquids will remain hot for a long time.
Functions
The top is easy to open with one hand by pressing on the white button marked InchPRESSInch. When carrying the flask, you can lock this button by sliding the white button down. A red area appears, indicating that the top is locked and it can no longer be pressed. The top has an integrated filter to keep large tea leaves or infused fruits out of your cup. Not suitable for very fine cut teas.
Care tips
Dishwasher safe (top + body) Be careful not to lose the top seals. Dry with the top off. The top's seal can be removed for a complete wash and dry.
First use
Rinse the entire product 3 times with clear water before using for the first time.
