I’m a big fan of Reduce tumblers. I have several different sizes including the 14oz for my daughter. They also make great gifts and are completely leakproof. This is actually more of a cup with a straw. I love that the metal piece keeps condensation from running down the cup can be taken off and washed to prevent mold. The rubber on bottom to keeps it from clanking when setting it down and keeps it in place. I love this sand color. The size is perfect for keeping by my bed at night filled with water. It’s actually designed perfectly for boba tea or thick smoothies with the wide straw. The glass is thick and seems very durable. This cup is unique compared to your standard tumbler and I would highly recommend.

I bought a pink one locally and my husband wanted one so I ordered from Amazon to get this color. We love this water bottle. The glass inside the metal means you can drink from glass without worrying about it breaking. The seal is surprisingly tight for the straw style and I have knocked it over multiple times without it spilling. The super large straw makes drinking lots of water easier, and the ring around the straw that makes it impossible to lose is a great feature. Has helped both of us with our goal to drink more water.

Reduced tumblers are my favorite ever! I purchased one years ago and was disappointed when it recently broke, (my fault). I love that they are glass, not plastic. The glass portion can be removed from the base for easy cleaning and it has a nice wide straw and keeps your drink cold for hours.

This cup is super cute. I love the color. And it’s the perfect size for my iced coffee. The straw is big and allows for easy drinking. My ONLY complaint would be that it doesn’t keep cold drinks cold for long. But it’s a sturdy cup and unless you’re going to take hours to finish your drink, it’s great!

This is my third Reduce cup. The other two are the traditional insulated style with handles, a big 40-oz. one for me and a kids’ size for my daughter. I love how they all, including this one, go in the dishwasher and come out still looking shiny and perfect. I’ve mostly been using this cup for water since it’s winter, but it is the ideal iced coffee cup, and I can’t wait to use it all summer. The wide straw also makes it great for smoothies. The lid sits very securely inside the cup and the aluminum and glass combo keeps drinks very cold — although ice won’t stay frozen long, so it’s chilled but not freezing cold. Funny enough, I find that I’m drinking more water when using this cup either because I can see the water or the way it fits so comfortably in my hand, or both. The matcha green color is dreamy too. Love it!

These travel coffee cup separates into two pieces, the glass cup and a smaller metal cup that it nestles into. The metal cup could be used without the glass but the glass can’t be used alone. The metal outer cup is intended to keep the liquid inside the glass cup cooler, but I don’t think it’s particularly affective. My two biggest complaints about this cup are the wide plastic straw, the kind you’d use with boba or a smoothie, and the lid, which isn’t particularly secure and comes off easily. Not my go to cup.

Llegó rapidísimo! Esta muy bonito, las perlas de tapioca negra pasan sin problema. Muy buen producto.

Se me ha caído alguna veces y sigue intacto, es muy práctico, el popote es muy fácil de limpiar y la tapa sella bien, lo recomiendo mucho

I have done brutally honest reviews on tumblers and this will be no different. Feel free to read the others.I am not paid by anyone for reviews.If you are clumsy or think you have more hands than you do, this is not the tumbler for you, or my spouse.BUT, if you are looking for something a little more "polished" or "swanky" this is a great choice.Obviously, this is not a typical tumbler. It has two main parts, one glass insert and one stainless steel powder coated reservoir the glass snuggles into. There is a silicone rim around the stainless part. This keeps the glass in place, doesn't let any goo from your kale-pumpkin-goat milk smoothie in the base and keeps that part of the glass contents cold.The straw is fairly large, I assume that is for smoothies/milkshakes. It is durable and substantial, not flimsy at all but you will need a wider straw cleaner because of the large circumference.The lid seems durable, again with a silicone ring to keep your contents in and not on your lap. It is easy to clean as it is dishwasher top rack safe, which is where I put it 7 times although the website recommends to hand wash all parts. The lid did NOT warp, bend, or crack from putting it in the dishwasher.The 18/8 Stainless Steel powdered coated reservoir/holder: The colour is amazing with excellent powder coating, and finally makers are realizing the important of a "grip" on the bottom of stainless tumblers so they do not clank every time you set it down much to the displeasure of others. The silicone grip on the bottom is substantial. How do I know this? I tried to rip it off the bottom with my hands just to test the durability. Yup, that is what I do. It fits in the standard grocery grabber cup-holder but not in the vintage Jeep.The scratch test. It scratches when a screwdriver drags itself down the side at a hard angle however there were NO scratches when I used a scrub pad on it repeatedly.The dishwasher. Yup, 7 times in the Top Rack of the dishwasher and it came out fine. However, I would suggest always hand washing as their website states.Tilt test: upon laying the tumbler down, water came out of the straw as expected but did NOT leak out of the rim of the lid which is great for the next time you knock it over whilst reaching for it thus throwing kale smoothie onto your newly carpeted office floor.Cold test: first off, its only insulated halfway so do not expect that goat milk to not curdle in 90F sitting on your deck for 3 hours. Realistic expectations are required. It kept my iced Java icy until I consumed it all albeit 4 hrs. later because I accidentally left it upstairs, forgot where I left it and wandered around for 4 hrs. looking for it. So, ya, it kept it cold and there was ice still in it. My house is always 64F.The glass insert: This appears to be lead free, BPA and Phalate free according to their website. Its glass. It holds liquid. It holds the lid perfectly with no flaws in the rim of the glass making it safe to drink directly from the glass without the straw/lid. There is NO odd taste from the glass and the weight of the combined unit is fine. It’s not heavy like some tumblers and is actually very functional for what it is.Remember, this is based on what it IS, not what it could be. So, for a 2-piece 1/2 stainless/glass unit, it’s a 5.Go up a notch and put that drink in an elegant Tumbler so everyone can see it!

Love this for my iced coffee. Do yourself a favor and get one (or three) now!
