Granted the Hopper 18 only weighs 5.1 lbs. vs 14.3 for the Cobalt 25, and the Hopper is easier to carry, but the Cobalt will keep ice for 2.5+ days with highs of ~73F, while the same amount of ice, food & wine in the Hopper lasts about 1 day. The latches are good quality and the Cobalt is much easier to open than the zippered Hopper. My only complaint about the Cobalt is that the handles rattle against the ends of the cooler loud enough to hear when it's riding in the back of my station wagon. This was a very minor issue and easily solved by adding a couple of stick-on clear rubber bumpers. I would definitely buy the Cobalt again.
Was excited to buy but the topper has been nothing but issues. It does not perfectly fit the lid of the cooler, measurements are off by about an inch. Also it has been warped due to extended storage being folded, it constantly peels up from the corners. The glue used simply isn’t strong enough to hold it down. Overall, not impressed and not worth the money. Would not buy again nor recommend.
It is probably too early for me to write a lengthy review of the Cobalt 55 but here's what I can share: I needed to find a robust, wheeled cooler to fit a specific cargo rack. The Cobalt 55 isn't the cheapest on the market but definitely not the most expensive. The cooler handle so far feels very strong and can handle the heavy load of a filled, roto-molded cooler. The wheels are performing great too, they are not like the flimsy kind found on cheaper brands and models. Blue Coolers does a great job marketing to families as their promotional videos are great! I hope I am able to still rate the cooler 5 stars, 5 years from now. Thanks again!
It’s a great lil cooler wish the 55 came in the tan.
These retro chairs hit the mark in all phases, size, light weight and great color pattern.
Kept our food & drinks cold at burning man. We kept it in the shade and raised above the ground. We did top off with ice every few days, but not much. – I recommend "white" because in tests that color stays cooler over time.
