I bought this tray specifically for my narrow water bottle, and it does the job well. The four long cubes fit right through the opening instead of getting stuck like regular cubes. The silicone is flexible, so twisting the tray pops them out without cracking or fighting me. It's also top-rack dishwasher safe, which saves time. The blue marble look is a nice bonus. If you want long ice for bottles or highball glasses, this is a solid pick.
