Totally worth the money!
These are so great that I i8mmediately bought second one in another color. Keeps my water cold all day. Comes with two lids, two silicone straws covers, bottle brush and straw brush. Can't beat that for the price! I will more than likely buy a third since they are such a good value. Nice bright teal color. Good size and fits in a car cup holder. I love the silicone sleeve for the bottom so it doesn't slide around. I highly recommend.

Best 40oz Tumbler and Price
I purchased 4 of these tumblers, 2 for me and 2 for my daughter. The colors I purchased are beautiful, Eucalyptus, Chambray and 2 Rose Quartzs. I picked these because of the 2 lids, colored silicone straw tips and silicone cup bottoms. I keep the metal straw in my cup and decided to fold it to connect it with the straw hole cap. I not sure if you are suppose to do so, but I want to make sure my drink stays cold and don't spill when the cat tips it over. Cleaning is easy while removing the silicone tip is a challenge. My drinks stay cold for hours. I find myself drinking more water daily. The handle feels smooth and the cup feels textured. The colors are matte pastels. The only problem I had was with the screws on the handle scratching my hand. I just replaced some of then, made sure they were screwed in straight with no damage to the screw head from the screw driver. The angle of the handle made it a bit difficult to do. I am so happy I had so many extra screws that fit. This explains why so many people have the same problem with the handle. I love my cups so much.

Great cup
This product works very well. It's very good quality. This product is very easy to remove from packaging. It is made of very good material. It is a great value product for the cost. Holds ice very well. Keeps drink cold all day long.

Great cup, not so great lid.
Overall, this is a great tumbler for the price! The only complaint is the lid quality. I work with kids so I don’t use the straw component. The opening to drink from does seal the lid. The rubber insulation works 95% of the time, but that other 5% the cup will leak from the seal (where the lid meets the cup). Also, the plastic lid does crack easily. Luckily, it took 6 months for the lid to completely break (after a few falls)…however, I am grateful that the cup came with an extra lid. I wish you could order lids separately, but for the price I’ll just get a new cup when the time comes.

Excellent Insulated Travel Cup
This cup has been, and still is, AHmazing. It keeps ice water cold for hours. As in 8 to 10 hours overnight. The ice cubes are smaller but they're there and the water's cold. I recently dropped it (sideways) onto our concrete driveway. The only mark was a scuff was on the plastic lid. A scuff vs. a broken lid makes an impression on a cup that gets knocked around a lot. Does it leak every time I knock it sideways? Nope. BUT, it leaks about half the time. It's a cup, filled with liquid and has a plastic lid with a metal straw. It's not vacuum sealed. It. Any brand of cup that's similar in design.will leak.Think about it. So, at almost half the cost of the popular name brand, this is/has been a *worth the purchase* insulated metal cup. I'd buy another one tomorrow if needed.

5-star Tamarac tumbler: leak-proof, durable, keeps coffee hot—recommended!
I’m obsessed with this Tamarac 40 oz Tumbler—5 stars without hesitation! First, it’s 100% leak-proof: I toss it in my bag daily, and not a single drop spills, even with the straw lid. The stainless steel durability is impressive too—no dents or scratches after months of use. The 40 oz capacity is perfect for all-day use; I don’t need to refill it constantly. It keeps my coffee hot for 6+ hours (game-changer for busy mornings!) and stays comfortable to hold thanks to the ergonomic handle—no slippery grips or hand fatigue. The color is vibrant and doesn’t fade, looking as good as new. It’s not just a tumbler, but a great gift too. Highly recommend!

Not quite perfect - lid needs a redesign unless you want a bath!
Ordered in the light purple. The color is pretty and the handle is comfortable. Nice that it comes with an extra lid and both a BPA free plastic straw or metal straw. That being said, this mug has a poor lid design. If you use the straw in the designated straw holder, you have to leave the sip cover open. Otherwise there is no vent hole. I figured this out when I filled up my mug and shoved the straw in. Basically it shot about 1/4 cup water right through the straw and into my face. Not cool. Also, I am not loving the straw being completely vertical in the center of the lid - if you're on the shorter side like me, the mug is already large to handle, now you have to have it at a strange angle to sip. The work around is to plug up the straw hole and shove the straw down the sipper hole - it just fits. Then you can have the straw slightly angled at the closest edge of the cup which makes it more accessible. I am disappointed in the lid design and having to come up with a work around makes it a poor value for the money. I will return it because of this design flaw and get the Yeti 42 oz straw tumbler - I have the straw lid for the 20oz tumbler and love its function.

Good cup with accessories for the price.
Great cup. Comes with extra straws and lid which makes it nice. Appears more sturdy when the silicone sleeve is used at the bottom. The 1 thing that's good and bad is that it is air tight when using the straw, but being air tight, when you close the lid, it forces the fluid out the straw. I took the rubber seal for the straw off the lid to fix problem until I come up with fix. Appears to keep drinks cold and nice cup with accessories for the price.
