Review on 20Oz Glass Tumbler With Silicone Sleeve, Stainless Steel Straw And Lid - Ideal For Water, Juices, And Beverages - Durable, BPA-Free Drinking Tumbler by Derrick Wilson

This tumbler is exactly as expected, the quality is solid, the materials are basically silicon and glass and so I have no concerns about any weird plastics that I'm drinking out ofThe borosilicate glass is thick and it does not look like it would shatter easily. It holds both hot and cold liquids equally well and I like the lip of the tumbler which does not have any threads and is easy to drink from. The lid stays on the tumbler and isn't loose but isn't tight enough to make this tumbler waterproof so this should be kept upright on a desk or in the beverage holder in your car. All parts of the tumbler are dishwasher safe and look like they would last a long time.I would recommend this tumbler to anyone who's looking for a solid and high quality reusable tumbler.
