## Description

desertcart.com: ecoBrew 16oz Double Wall All Glass Tumbler with Lid, Dishwasher Safe & Microwavable Glass Travel Mug, Clear Coffee Tumbler To Go, Reusable Ceramic Cup for Hot & Cold Drinks : Home & Kitchen

Review: GET one of these! - EXCELLENT product! The glass is very thin, but the tumbler is designed well. I'm always amazed that I can pour such hot water in without it breaking. It hold the heat well, too. I don't use the dishwasher, but I find it easy to clean by hand. I don't use the dishwasher, I purchased a separate silicone tumbler sleeve with handle, reducing my concerns for the tumbler's delicate all glass construction. But it's the glass that I wanted, and ecoBrew delivers! I've had this and used daily for months. Great value for the money.
Review: Broke When Using It/ Merchant corrected with full refund - I changed my rating from 1 star to 5 star. The merchant corrected the transaction with a full refund and I didn't ask, Surprised me. Definitely would do business with them again. They stand by their product.

### ⭐ Disappointed.
*by D***E on December 16, 2025*

I really wanted to love this cup. I bought it as an early Christmas gift for my mom, and she used it for the first time today. When I went to wash it, I twisted the lid off the way anyone normally would—and the glass cracked. A piece of the glass actually cut my hand. This was extremely disappointing and honestly unsafe. A cup should be able to withstand normal use, especially something as basic as removing the lid. Sadly, I wouldn’t recommend this product due to the quality and safety concerns.
