Review on Large FEO Packing Set Sports Bottle with Thermos Vacuum Insulation by Robert Goodlow

They are only 2mm larger for a thermos. I bought two sets and both keep falling or slipping when I unscrew the thermos caps because they are slightly larger in diameter than the original caps that come with the thermos. Good quality, looks the same as the originals, but when they are too big and keep falling out, it's frustrating and uncomfortable. I'm afraid they might leak if I try to trim them to fit. THAT'S A LOT OF MONEY FOR SMALL SILICONE PADS. But what will you do? Spend $5 on them or $25 on a brand new thermos? By the way, I've already tried 8 such thermoses: some stayed in their places of work, while others just cracked badly because they fell from the scaffolding. But I believe in these thermos flasks! The absolute best way to keep iced drinks cold for 4 hours and even hours while sitting in the sun! You can't beat this so I'll keep trying to find better pads elsewhere if they even exist.
