Tronco 20 oz Glass Tumbler with Lid and Straw, Reusable Iced Coffee Cup with Silicone Sleeve & Bamboo Lid, Smoothie Cup for Home, Office, for Father Men Day Gift from Wife Daughter Son (Black)

Great quality! Love the color and thickness of the bottle. Keeps drinks cold and washes up well. I always hand wash it. The lid stays sealed. I use it in the car daily. I would buy again and give as a gift!

I love that this is glass with the silicone covering. It's a good thickness over the glass and makes it easy to hold onto the bottle plus the covering goes under the bottom too, so it serves as it's own coaster to prevent water condensation from touching furniture. The lid pops on and off easily enough, so it's not difficult to refill or clean the bottle. I also like that the bottle has no ridges or anything harder for me to clean with my bottle brush. And it came with two straws, not just one! They are very sturdy straws with some flexibility, so it's not like those steel straws that you have to angle your mouth just right to drink or feel that slight fear that you'll somehow stab yourself in the mouth with it. Overall, a really good product that I'm very happy to have purchased.

I love this tumbler! I drink a lot of smoothies and was looking for something slim, made of glass, and easy to carry around. This tumbler checks all the boxes — it’s sleek, lightweight, has a good cover, and is easy to take with me wherever I go. It’s exactly what I needed and serves the purpose perfectly. Highly recommend

I’ve been using the Tronco 20 oz Glass Tumbler daily for iced coffee and smoothies, and it’s quickly become one of my favorites.What I Like:The glass combined with the bamboo lid and silicone sleeve looks sleek and modern.The silicone sleeve provides a secure, non-slip grip, making it easy to carry around.It works well for both hot and cold drinks, though I mostly use it for cold beverages.Being reusable and BPA-free makes it an eco-friendly choice.What to Keep in Mind:The tumbler is water-resistant but not fully waterproof, so avoid submerging it completely.The straw is a bit stiff at first, which can make sipping slightly challenging.The tumbler is dishwasher safe, but the bamboo lid should be hand washed to last longer.Bottom line:If you want a stylish, practical, and eco-conscious tumbler for everyday use, this one is a great pick.

Overall, this is a nice set of tumblers. The glass is thick and heavy (almost too heavy for me when it's full bc I have joint problems affecting both thumbs). The silicone is smooth and thick, with no weird little tags/nubs from molding that stick out. Seems like it would not tear easily. The lid seems well made... very smooth wood or bamboo, and doesn't seem like moisture between the wood and internal silicone fitting will be a problem. A few minor things keep it from being five stars (on paper, anyway) for me personally.First, the straws are rigid plastic, very fat, and not quite long enough for my taste, so I use my own silicone straws instead. And as the straw hole has silicone to hold the straw in place (see photo), switching straws isn't a big deal. It's also soft enough of a fit that if you needed to use a disposable plastic straw from McDonald's, it wouldn't collapse the straw.Second, the silicone fits on the glass like a sleeve--it's not a permanent integrated part of the drinking vessel. But there doesn't seem to be any way to easily get it off and on, so I don't know what you'd ever do if water got between the sleeve and the glass and created mold. These are for my personal daily use, so I'll just rinse them out from my herbal iced tea whenever I'm finished using them, and they'll be good to go for tomorrow. But washing *could* lead to problems if you need to submerge it in water, like if you put smoothies or protein shakes in it, then need to wash it in a sink full of dishes. (It also has a hole in the bottom [see 2nd photo] to *theoretically* facilitate sliding the sleeve on and off. This hole provides another way for water to potentially seep under the sleeve during washing.)Third, if you track your fluid intake and are an anal retentive nerd like me, if you use it with the lid, it only holds 19 oz. You can't fill it up all the way to 20 oz and still use the lid without squirting a bunch of fluid out the straw hole, taking you back down to 19 oz. Yes, I measured. LOLStill, I really like these tumblers. Money well spent. And for me, the detractions aren't worth knocking off a star.UPDATE: Six months later and they're still great! Still using my own silicone straws, and the straw opening in the lid has not distorted like someone mentioned in a review happened to theirs with the included hard straw. The bamboo lids are in good shape, no drying or fraying or splitting. Washing has not been a problem. A tiny little bit of fluid might get between silicone and glass, either during washing or when pouring a drink out of a jug, but no mold/mildew has developed due to this little bit of seepage. They have been through the dishwasher many times, and handwashed in a sink full of water a few times. Still really pleased and would recommend these!
