Kollea 18/8 Stainless Steel Tumbler Double Wall Vacuum Insulated Travel Mug Water Coffee Cup for Home, Office, School for Hot & Cold Drinks (Black)

The slider on the lid broke off after a few uses, but the rest of the tumbler has held up well for over 5 years.

These work great. I purchased two... I keep water in one all day - rinse it out-while it's drying thoroughly I use the other... to help prevent rusting that does occur sometimes at the seams of these types of thermal tumblers. NONE so far with these - but as I said, I careful clean and use them. NO DISHWASHER - even it says they can. I will say I have filled one with ice added a little water and then used out of a hot car ALL day. There was still ice in the glass after more than 9 hours. That is impressive to me. They did come with little cloth sleeves.. I was initially confused by this as these tumbles are not supposed to "sweat"... and they do not sweat! So... I am thinking the sleeves are an "easy" grip thing and also helps it to be stable in cup holder. The plastic tops have rubber like gaskets and a slide opening. The slide doesn't really stop water from pouring out - but it does slow the process. It will keep foreign objects out of your water! :) I never hesitate to update my reviews should new info seem useful.. and I did wait to use these for a while to be able to share actual use experience. I hope this info was helpful to you in making your decision as that's the whole reason I bother to write unbiased, uncompensated reviews!

I like tea, but I'm really lousy at reading that magic spot between too hot and too cold. Either it will melt my mouth off or it's suddenly iced tea - which is also tasty, but not at all what I was going for.Enter a magic tumbler that understands my wants and needs. It arrived in an unassuming brown box, obscuring the awesomeness within. It's a stainless steel tumbler with a plastic lid that holds a metric s-ton of hot, tasty tea to help get me through the day (robust & caffeinated) or relax at night (fruity & herbal.) If it's too warm, the lid can be removed for a little bit, putting it back on when it's the ideal sippable temperature, and it holds it that way for a much longer time than the average kitchen mug. (Though props to thick ceramic and stoneware for holding the heat longer, much love for your service through the years!)Cons? If you tip it over, even with the plastic lid shut, it will leak. But that's more of a "don't knock this over" sort of deal than an expected use.I plan on using it at home, so the thickness for cupholders won't be a factor to me, but this is a stout tumbler, I can see how it may not fit all vehicles.

Been using one of these daily for 2 months for my morning coffee routine on my commute and beyond. Initially I didn’t like it because the 30oz size is really surprisingly huge and it felt uncomfortable to hold in my hand for more than a few minutes. Over time I got used to that, and it’s more comfortable if you take off the black neoprene sleeve that comes with it. The unexpected benefit of the huge size is I can make coffee just once in the morning and it holds enough liquid and stays hot long enough that I don’t need a refill until noon or later which saves me the wasted time of a late morning refill run. I’d say it’s holding up average or better to wear. I hand wash the stainless tumbler itself which shows zero deterioration so far. I put the plastic lid in the dishwasher every night and there is no significant deterioration but unfortunately the slide on the lid is starting to move a bit too freely after 50+ washings — sometimes it closes itself with gravity when I tip the tumbler to take a sip. This is annoying but all the other tumblers I’ve tried also eventually have issues with the lids and at $10 this Kollea appears to be a great value versus similar products that cost 2-4x. Maybe if you have particularly small hands the discomfort of holding the 30oz size would be too much but otherwise these seem great for the money and I will buy more over time if I can’t figure out a way to make the slide on the lid hold its position more securely after a lot of washings.

I personally love the fact that this tumbler is large. The lid fits securely on the top, but it will leak out if the tumbler leans at a certain angle. The tumbler, like shown in the photo, comes with a black sleeve, which came in handy when I poured a freezing cold smoothie in there. My hands did not feel cold at all. And this will help for the winter when I want to use this for hot soup. I love the fact that this tumbler can keep hot soups. I got about 3 hours of my smoothie being very cold until it started to become room temperature. It is pretty well insulated, but not the best on the market for insulation. As for the durability, this tumbler has that covered. The cosmetic appearance is also great, so this is something I could see being given as a great gift with no problem. I noticed after I washed it, a little abrasion took place on the exterior. It was not rust, but it resembled what rust would look like. I only say this because I read another comment that mentioned rust. I am not sure what this is. It actually came with a bit of abrasion on the exterior as well. I really don't know what it is, but if it gets worse I'll update my review. I don't think it is rust, though.The top is durable plastic which you can remove to pour in contents.

This whopping 30oz stainless steel tumbler is great for the price! It's in direct competition, in my eyes, with the Yeti and this one comes out the better, cheaper and larger one. Definitely snatch this up when it's on sale with Prime!The sheer capacity of this thing is great, but that's not all. The lid is also sturdy, as it has black rubber lining around the top to prevent spillage. It can also keep any drink hot or cold for many hours, averaging around 5+ for us. My husband used it for work and had NO complaints.The only thing I will say about it, which happens to be a bit on the negative side, is water can get trapped between the slidable pieces on the lid. So long as you let it dry out, it should be okay. On the plus side, it's clear plastic so even if weirdness starts growing, you can clean it when hand washing. I would not recommend placing the lid in the dishwasher unless you use a no-heat cycle!Overall, the tumbler is totally worth it. Buy it!
