Third, the product details

After receiving the product, after opening the package, in addition to the cup and instructions, the package also provided a personalized sticker, coaster, membership card and cup brush, etc., supporting supplies are complete.


The first thing that caught the attention was the illustration on the black deer flask, which was very eye-catching. I remember that the last exposure to such eye-catching outdoor products was a Sparkt jersey.

This illustration is named dry, meaning that if you bring yourself, young people will dry up. The illustrations are brightly colored and colorful, and they look carefully with some Picasso styles. They have painted a little quirky elf pattern and are very vivid.



The cup cover is made of PP material that does not contain BPA to ensure that the material is harmless to the human body. The built-in silicone gasket can enhance the sealing performance and improve the heat preservation and leakage prevention.



The top surface of the lid is a "Yan-style" design. The top of the original flat lid is lifted and pressed down symmetrically. This makes the lid full of three-dimensional, with a product LOGO at the center of the top and a symmetrical flank on the side. Waist treatment for finger grip.



The black deer flask's portable design adopts a horizontal cutting edge design, and the finger contact part is curved, and a widening process is performed to ensure the comfort of the hand-held device.


The black deer mug cup body is made of imported SUS304 (18/8) stainless steel. The cup mouth is polished and the lips feel comfortable. The 304 stainless steel is safe and non-toxic. It is suitable as a food container. The large-diameter design can be easily cleaned and smoldering.


The size of the cup body is larger than the one before me, and the diameter is 7.9mm. Fortunately, my hands are relatively large and can still be easily held.


The bottom of the cup uses the original color of stainless steel printed with the relevant parameters of the flask, including capacity, material and so on.


Due to the double cup wall and hollow cup design, the weight of the cup body is not heavy, 335g - an acceptable weight.


Fourth, the actual use:

Indoor testing: At the end of the year, it is ready to take it to the northeast, so I particularly value its insulation performance. In order to test the thermal insulation performance of the insulation cup, I filmed a set of videos, put the hot water in the flask on the outdoor (about 0°C minimum temperature outside the room) at around 9:00 pm and retrieve the insulation cup at 7:00 am the next morning. It was found that the water is still too hot to be drunk. It will continue to be stored outdoors. It will be taken back at around 9:00 in the evening. The temperature can be directly imported and it will not feel cold.

Simmering test: At about 12:25 in the evening, pour boiling water into the cup and preheat it for 5 minutes. Then put the rice in the cup, pour it into the boiling water and shake it, let it stand, and open it at 7:00 am the next morning. When the rice is poured out, the rice is already rotten, and the taste is not much different from that in the pressure cooker.

Cycling Use: In view of the last room insulation test, if you only bring this one cup, the one-day itinerary is definitely not available. I choose to use a GSI open cup to pour the water in the flask first. Into the open cup, cool for a while and then drink just right; in addition, the open cup is also convenient when cooking rice, the warming cup can not be eaten directly after the rice is finished, you can pour it into the open cup first, and then use the spoon to eat .

For camping use: After a busy week of work, bring family members away from the hustle and bustle of the city on the weekends, go to the field and let yourself go and enjoy the beauty of nature.


V. Summary:

As a thermal cup, the excellent thermal insulation capacity is relatively cost-effective compared to the price of less than 200 yuan. No less than 12 hours of thermal insulation fully meets the current requirements of my use, and the kettle is excellent workmanship. Security, stunning appearance, if you score it should be able to hit 9.5 points.

It is worth noting that after the porridge, the rice grains stick to the bottom of the cup. If it can be provided with a long handle spoon, it is believed to be very practical.

Written in the final: I plan to bring it to the Northeast (Harbin, Mohe) by the end of the year. Then I will experience how it performs in the real extreme environment. I hope it will bring me a surprise.
