Review: Excellent Quality and Insulation, but the Carry Cover Could Be Better - Product: Coolflask 128 oz Gallon Water Bottle Used for: 1 month and 3 weeks Key Features: – Large 128 oz capacity for all-day hydration – Durable stainless steel build with solid insulation – Comes with multiple lids for different uses – Carrying sleeve with strap for portability Ratings: Quality: The quality of the bottle itself is excellent. It feels premium, well-built, and the insulation works great. I’ve only used it for cold drinks, but it holds temperature impressively well. My only complaint is the carrying cover—it feels a bit cheap, and the zipper on mine already broke. A higher-quality sleeve and handle would really make this perfect. Rating: 5/5 Performance: Day to day, it’s been great. It holds cold temperatures for a long time, doesn’t leak, and the different lids all function smoothly. The bottle is large but manageable, and everything feels solid in use. Rating: 5/5 Value: It’s not cheap, but for the quality of the bottle itself, it’s worth it. The insulation, design, and durability justify the cost. The carrying case could use improvement, but it doesn’t take away from how good the bottle is overall. Rating: 5/5 Pros: – Excellent insulation and temperature retention – Strong, durable construction – Multiple functional lids – No leaking issues Cons: – Carrying cover feels cheap and zipper broke early – Could use a sturdier handle design Summary: The Coolflask 128 oz Gallon Water Bottle is a fantastic, heavy-duty option for anyone who needs to stay hydrated throughout the day. The insulation is impressive, and the build feels premium and solid. While the carrying cover is a weak spot, the bottle itself more than makes up for it with performance and quality. If you’re serious about your hydration, this is worth the investment. Overall Rating: 5/5 Disclaimer: This review is based on my personal experience using the product. I’m not an expert—just sharing my honest thoughts to help others make an informed decision.
Review: Great quality, full functionality, flexible options for use - I've tried various insulated coolers in various sizes. This Coolflask 64 oz is perfect for my needs be it exercising, yard work, or just next to my desk. The Coolflask has no problems keeping ice and water cold, often for more than 3 days. It saves a lot on individual water bottles and trips to the frig to refill. This flask is nicely made and comes with various options for use along with straws and a nice cleaner brush. I have not had any issues with leaks. I did reached out to Customer Service for a small issue. Their response was unbelievable in today's standards. I heard from someone in very quick time and it was on a weekend. We discussed my issue and it was resolved in a very short time to my complete satisfaction.
