Duro Kent Insulated Stainless Steel Flask Water Bottle For Daily Use 750 ml, Military Green | Double Wall Vacuum Insulated 24 Hours Hot & Cold Thermos Water Bottle For Office School Gym & Travel

I recently purchased a Cello water bottle, and I must say it has exceeded my expectations. The build quality is outstanding – sturdy, durable, and completely leak-proof. The design is sleek yet practical, making it easy to carry anywhere, whether to the office, gym, or travel. The bottle keeps water fresh for long hours, and the material feels completely safe and hygienic. What I love most is its lightweight nature combined with a stylish look. It’s also very easy to clean, which makes it highly convenient for daily use. Overall, Cello has once again proven its commitment to quality and customer satisfaction. If you’re looking for a reliable, long-lasting, and elegant water bottle, this is the perfect choice. Highly recommended! ✅

The bottle is really good. It is storing cold or hot water atleast for 12 hours. Easy to use due to small size.

Verry good quality

I filled the flask with a dozen pieces of ice along with cold water at around 10pm. Next day morning there was still ice inside. The outside of the flask wasn’t wet either condensation either. It was room temperature. Very good. At approximately 10:00 PM, I filled the flask with a dozen pieces of ice and cold water. The next morning, there was still ice inside the flask. Notably, the exterior of the flask remained dry, devoid of condensation, and maintained a room temperature. This outcome was satisfactory. The bottle fell from the table and only a slight dent. Bottle is very durable and well made. Highly recommend

Very bad product, and very bad services of delivery man, if we want to replace it, they will not replace it, if we want to cancel it, nobody comes to take it ,very bad condition of amazon delivery, return, exchange item, it's very irritating

Good quality and stylish, easy to carry,capacity is sufficient,long time warm water

I purchased this bottle along with bottles from Pigeon and Sumeet to compare real-world cooling performance, durability, and overall usability. After using all three, I can say the Cello bottle delivers good build quality and durability, but its insulation performance did not justify the higher price for me. The bottle feels premium in hand, with a solid stainless steel body and a quality finish. It also looks better than many budget bottles and feels more reliable for rough daily use or travel. In terms of durability, Cello is clearly ahead. I already own a year-old Cello Maestro Thermosteel Flask that once fell from a moving car and survived with only a small dent while still performing normally. That gave me confidence in the brand’s toughness. However, the actual temperature retention was disappointing compared to the Pigeon Bottle. In my usage, the Cello Duro Kent retained cold water for around 11+ hours, while the Pigeon bottle managed 20+ hours under similar conditions. Considering the Cello bottle also costs more, this came as a surprise. If insulation performance and value for money are your top priorities, Pigeon clearly performs better in my experience. Compared to the Sumeet, the Cello bottle is much better in overall reliability and cap quality. The Sumeet bottle developed cap issues during the very first use, where the cap would endlessly rotate instead of tightening properly. I had to return it immediately. The Cello bottle, on the other hand, feels dependable and well-built with no such issues.

This is an excellent bottle. The colour is exquisite and it can keep water at the right temperature. I believe the build quality is durable and it certainly doesn't leak at all. I bought the 900ml one, which is already quite heavy even when empty and weighs around double when full. It is possible that the 500ml and 750ml might be better for everyday carry, though I wouldn't recommend the latter for strenuous outdoor activities such as hiking.

Keep hot things hot and cold things cold

The design is not good. Water leaks out of lid when opening. Need to keep away from clothes when opening the bottle. Not fit for office use. Should have tissue paper or napkin ready whenever you want to drink out of it. Not recommended due to design flaw.
