40 oz Tumbler with Handle and Straw, vacuum
This tumbler quickly became my favorite. It arrived packed so well and felt high quality from the start. The color is beautiful, the handle is strong, and it keeps my iced coffee cold for hours. I kept checking because I couldn’t believe it. The lid doesn’t leak, and I love that it comes with two metal straws and a brush. I’ve been using it every day since it arrived, and I honestly love it. Definitely worth it!

Really nice insulated cup
This is a 40 oz tumbler with a comfortable handle and wide opening. The opening can be opened for sipping, inserting a straw or closed. This comes with two stainless straws, one straight, one bent. The description states that this has “…Double-wall vacuum insulation keeps beverages cold for up to 27 hours and hot for up to 13 hours. Powder-coated, sweat-proof exterior and silicone base provide stability and help prevent slipping…”. I have no reason to doubt this claim. The description also states that this tumbler should fit in most vehicle cup holders. I can confirm that it easily fits in our ’25 Hyundai Santa Cruz. I do like the addition of the silicone on the bottom. Others have a tendency to move around easier than these do.There is one thing that is really confusing in the specifications page. On this page the following is stated: “…Dishwasher Safe, Hand Wash Only…”. This has my curious mind really going in circles. So, is it dishwasher safe or hand wash only? Boy, let me tell you, I think I might just have the answer, because, you know, I’m so smart! 😂🤣 I thought, and thought – must’ve been an hour or so, but then again, who has a watch these days. Finally, I think I figured it out! Before I show you just how smart I am, lets first look at the statement. I think it actually two statements. Dishwasher-safe And Hand Wash Only. See, now it makes sense, huh. So, to test my theory and provide a great review, I gathered up all my equipment and commenced to research’n.Cup, check, Straws, check, lid, check, Dishwasher, hmmmm. Momma just left to get firewood and feed the cows & critters. What am I going to do without my dishwasher. I mean, shes the best there is in these parts. Let me think….. Hey, I think I’ve got it. We have us one of them fancy clothes washers, you know, the kind thats got them rollers on them to squeeze the water out and dry your clothes! It does a great job on clothes, so I’m think’n it Must do a great job on anything else that needs cleaning – See, told contraption I was smart! So I decided it would be a real crime to only wash one thing, afterall momma just hauled up all this water from creek before she left to get the firewood! So I looked around to find some more dishes to clean. What do you know I spied those wedding plates we got when we got married! We ain’t used them in a good long while, so I decided to use them. Besides, them flat plates should be really easy putti’n through that there fancy roller dryer – see all that smartness? I must be thinking real hard ’cause I’s get’n a headache. But, on with the review.I gathered up all them there plates and stuck ’em in the new found dishwasher with this cup and turned it on. I’m not really sure what happened next, but there sure were some loud sounds coming out that there dishwasher. But after ’bout ten minutes, it quieted down. Must’ve been a squirrel or something. After it finished up, I went in to look at how clean everything was. I looked i side and ’bout hit the floor. There were only one plate in there along with the cup! There were a bunch of pretty rocks on the bottom too – odd, but them rocks sure remind me of of those wedding plates, I’ll need to figure out which creek they come from so I can get more of them. 😎When I looked at the cup, it looked like somebody hit it with a bunch of rocks or maybe a hammer! That got me thinking again. Oh No! That pesky thief is back again, he done stole them plates and must’ve dented up the cup! No I was on a mission. That thief and me have had issues before in some past reviews! I’ll have to take care of him later though, ’cause I gotta git this review done!As I looked at dis cup all dented up, I noticed how purty the pink was (or used to be) on it. The handle is big & comfy too! As far as the dishwashing, I think you should be safe and wash these by hand.When I first received this item I did my typical initial inspection and didn’t find any major issues or defects that would render this unusable. At this price point (~$25), I believe this is a good value. However, currently there is a coupon available for $3.75 off the current price. When the coupon is applied, this makes this price a really good value. A quick search shows similar items costing between ~$25-35, with big names costing $45+. Would I order this again? Yes, I believe I would.Hope this helps, or at least puts a small smile on your face!

Has a really solid matte feel
Feels heavy and solid, I like that the lid has the different ways to use it, with a straw or open/close to sip. I was happy it actually kept my drink cold I filled it like halfway with ice and then a soda from the fridge, it still had ice and fizz when I finished it about 12 hours later while using the straw in it so I’m sure it’d last a bit longer if closed, and I still had ice so could’ve gone longer. It’s a really pretty matte feeling pink, comes with two stainless steel straws and an extra long straw brush to clean with. Big fan!

Fits perfectly in my car!
Love this tumbler! The handle makes it super easy to carry around, especially when I have my hands full with my keys and phone. Keeps my water freezing cold all day. Fits perfectly in the cup holder of my Toyota. Will definitely be buying another color for my husband.

Better than the expensive ones lol
Okay so I left this tumbler in my car for like 2 hours while I was grocery shopping (and it is COLD today), came back and my tea was still steaming? Honestly, for the price, you can’t beat it.

Excellent tumbler
I love the cup! I left it in a hot car all morning and my water was still cold. it’s GREAT for my simple water intake needs. I use it daily. It’s simple in design and does the job! Keeps my water relatively cold when I put ice in it. Works great when I want room temperature water during colder months. The straw is strong and not flexible. Heavy duty, too! Close feature on top so if using without a straw it won’t leak. Excellent price for the quality! Especially compared to very similar items with a price point four times as much. This will last me quite a long time!
