Review on 🥇 SassyCups Best Mimi Ever Tumbler: Engraved Mint Stainless Steel Insulated Tumbler for Mimi, Mimi-to-Be, and Mimi Grandma! Great Mimi Birthday Presents! by Jeffery Pricinoc

While the cup is cute and definitely strong, I find the lid very difficult to attach securely and impossible to remove. Apparently the black rubber insert on the lid doesn't fit or doesn't fit properly. By removing and trying different ways to attach the rubber insert to the lid, I couldn't easily slide the lid in and out of the mug. In addition, the slide on the top for opening and closing the drinking hole is also very stiff. I can't imagine how easy it would be for her to use this mug if I gift it to a grandmother in her 60's or 70's.
