Everyone loves them

I ordered two and both of them work great. I do not have problems with them sealing or leaking at the seam. Don't overfill, it will expand out the top and make getting them out hard. Haven't figured out the perfect method to getting them out yet. Generally run warm water over them and just start pulling the top away from the bottom. Perfect size for my tumblers from Sierra TP and the ice lasts for hours. Not much else to say. Great quality, thick silicone. Will buy more for gifts.
