i fell in love with the beautiful and clever design! was afraid it wouldn't last warm bcs the bottle (especially the top) would get very warm after pouring the hot drink in. but surprisingly it lasted the whole night until morning for my breakfast tea. i appreciate the stainless steel on the inside of the top (my deal breaker). the only disappointment was a hard-edge transition of the design – visible in the picture i attached.

Although I’m not an astronomer, I’, now feel ing like one in my engineering research centre … :)… Very stylish and functional bottle.

This bottle is perfect, its durable, doesnt leak, feels comfortable despite its size and the print is even more gorgeous in real life! Perfect bottle!

I think that the bottle looks just amazing. It has a great weight for its size. I haven’t been able to test the bottle yet, as I’ve just been admiring the looks and texture of it, even slightly afraid of using it and then damaging it in some way.

The bottle looks great, print on it is also quite durable for a printed picture on a steel bottle. The colors are very accurate. The steel bottle itself is very durable and what i love about it is the handle on the top which makes it really easy to carry. Also very easy to wash. LOVE it!!

I really like the botanicals serial. The shipping was too fast which makes me happy. The patterns are so unique. I prefer to see discount code for the second order. But let’s save money for the future :)

Good product and a good customer service

I love this design! All my college at work complimented it.

Its the second time i bought a bottle here. I just love it. It holds cold drinks the whole day cool, it looks awesome, and the only negative thing i could say is that is not suited for sparkling drinks, but thats it. I had the bottle in a tote bag when a car drove into me as I was crossing the street, and the bottle took the brute force of the crash, and came out with only a small dent. I love it so much, it literally safed my a**

Botanical Pharmacy 950 mL Steel Bottle

Poisonous Plants 350 mL Steel Bottle

Core Sample 350 mL Steel Bottle

Really happy with this bottle. It keeps drinks warm for a long time, and it looks great. Build quality feels solid and premium. I would also recommend getting the straw cap addon, it makes it much more practical for everyday use.

The basket itself is well made, but it is not compatible with a large portion of the Cognitive Surplus steel bottle lineup, including the Heartbeat 500ml. This is not clearly communicated at the point of purchase. I asked customer service about compatibility before ordering and was directed to this exact basket without any mention of this limitation. The incompatibility is noted on the website, but requires careful attention to spot. I ended up with a product I cannot use.

Received This bottle wich looks amazing. It keeps your drinks supercold during a long period.
There was a small problem with the lid, reached out to customer service and was replaced within a week. Top service, top bottle, happy customer

I ordered an insulated water bottle as a birthday present for a friend, with a design that matches the recipient's profession and suited his taste. It was an awesome gift, he loved it!
(The only downside was the transport company GLS - a very poor delivery service. The drivers in our City (Vienna) refuse to deliver directly to the customer. Instead they drop the parcels at the next "parcel drop off station", so you have an extra walk or drive which makes the idea of ​​delivery absurd and leaves the end customer to do their work.) The customer service of Cognitivesurplus tried their best to support me on this. Although they couldn't help with the delivery stuff they were very polite and supportive !!! The product is so beautiful that you forget the hassle again!

Cette gourde est suoer jolie et qualitative! Ravie!

For me, as a paleontology buff, the design hit home. Delivery was fast.
It feels like a very good quality bottle. Not flimsy at all. The insulation is excellent. I love the design and the texture of it. This will serve me for years.

Genetics & DNA 500 mL Steel Bottle

I love it! It's pretty and it keeps the drink cold for a long time so I'm very pleased with this purchase ☺️ Would highly recommend

The design is as said sooo pretty and was exactly what I was hoping for. It keeps your drink cold/hot for a very long period of time and its super easy to clean. I didnt have a problem with the print either it stays on even if placed on a rough surface or if its in my bag. It also does not leak at all! Im incredibly satisfied with the product! Nothing bad to say at all.
