Review on 🔒 Magnetic Spill Proof Slider 2-Pack - Replacement Tumbler Lid for Yeti, RTIC, and Ozark Trail - Black 10/20oz by Roy Niemeyer

I have purchased several stainless steel insulated coffee mugs from two different sellers. I think they are 12 or 14 oz. Capacity. They're easy to use and clean, but one always has an open drinking hole and the other has a plastic slide lid that doesn't move smoothly. I just received these new lids and they are great. I ordered the '20 oz' size and it fits these 12-14 oz. cups are great The slider moves slightly and locks into place. It looks like a magnet is holding the slider. You can slide it forward and then push up from the bottom to remove it and clean it thoroughly. Now my coffee stays warmer with no open hole. The lid material feels thick and durable, and the rubber seal has a double rubber ring for a good seal. I would like mugs to come with this lid as standard, that's good.
