Review on ☕ SUNWILL 20oz Tumbler with Lid, Stainless Steel Double Wall Vacuum Insulated Travel Mug, Long-Lasting Insulated Coffee Cup, Rose Gold, Thermal Tumbler with Spill-Proof Sliding Lid by Kyle Ross

Easy to clean, comfortable to hold, comfortable to grip. I've been using it as my main cup for a few days and I can find both good and bad points. Firstly, I like the coating, it's not slippery like some of the other lenses I've used. I haven't tested the quality of the leak, but I can definitely say it's an airtight fit. I know this baby's BC is closed, I often find it difficult to close the lid! It confused me at first until I realized what the problem was. So if you're having trouble putting the lid on, try opening the spout! I love how it keeps hot drinks hot and cold drinks cold. He held the ice for several hours - at least 7 hours! I don't like two things. 1. If you want to drink carbonated beverages from this glass, I advise caution. Carbonation makes the top float. I thought opening the spout would prevent this, but it doesn't. 2. Liquid has accumulated in the lid mechanism. It's not really a problem, but it's not visually appealing to me. The lid washes very well under running water and drains by hand but not on the cup during use. These issues will probably make me look for another mug, but for everyday use it does the job so I'm still giving this product a four out of five.
