Funkrin Coffee Travel Mug with Straw & Flip Lid, 16oz Insulated Tumbler Cup with Ceramic Coating, Double Wall Vacuum Leak-Proof Thermos Mug for Office School Party Camping

I'm a slow coffee drinker, this is the way I enjoy my coffee, a sip here, sip there. When I'm home I'm constantly reheating my coffee in the microwave. I have a really big yeti that I take with me to work and it stays hot through half the day. However this is too big just to take with me in the car, so I end up taking one of those plastic coffee mugs that had to snap on lid. These are the same ones I used around the house and I can just put in the microwave for 45 seconds to heat up. The problem is in the car they only stas hot enough for about 15 minutes, then I have lukewarm coffee which I hate, I like my coffee hot. So I ended up getting this coffee mug and I'm wondering why I waited so long. First of all the quality is very good, it has a rubber base to it which I forgot to take a picture of, of course it's double walled, and the top has your standard straw or gulp option. Since I will likely never use this for cold beverages I just tested the straw out with some cold water and it worked perfectly fine. So I set out the test this for my specific needs. I had an appointment about an hour away from home, I made my large coffee (by the way this fits under a Keurig) and set out on the road. It can take me up to an hour or longer to drink my coffee and because of that the less and less hot liquid you have in the mug, the faster it'll get colder. So this was a good test, and the password flying colors, by the time I was about 15 minutes away from home over 2 hours after I had left the house, the small amount of remaining coffee will still warm enough for me to drink. So, definitely happy with the results. Of course a lot of people will simply fill this up in the morning and come lunch time drink it, I'm sure it would be piping hot by then too. So it works as advertised, it's made well, it looks nice, so what's not to like? Well, the only nitpick I have is it's a little bit skinny and it wobbles around in my car cup holder, there are many ways to remedy this, but it was worth mentioning. I'm not going to hold it against the product though, you can't design a mug to fit every cup holder. So I'm giving this five stars, I like it a lot and it's going to need my go-to on the go coffee mug.

I've been on the lookout for a good travel mug with 2-in-1 spout. This Funkrin mug is nice add on to our insulated mugs where you can use a straw for cold drinks, and on the other side you have a snap-on lid for mouth opening. One downside hence the 4 star is that it's not 100% leakproof—which is also common for most snap-on lid tumblers. I mostly keep it in my car or on my desk in an upright position and tested it by placing it upside down and noticed a slight leak despite closing the snap-on lid tighylt. Other than that, it's a good travel mug and the bottom has a silicone coaster to avoid accidental slip. The ceramic coating is absolutely perfect and will keep your drinks taste as expected. Lastly, it kept both my cold and hot drinks on their temperature.For its price, I think it could do better. Overall, it's a good insulated mug, the no-leak design is always a hit-or miss, but this mug is almost close to that.

I previously got a Funkrin mug that was a very similar style. It had one big problem, which was the design of the flip open lid. It pressed up against your nose and blocked your eyes. It was not a good desing.I am happy to say that this new mug is a much better design. It still has the nice ceramic lining which does not stain easily, but does clean up very easily. The size and style is not tippy, but still fits in most cup holders. The rubber bottom means you can put it down quietly without a metal klunk. The new lid has a separte sip opening with a straw, or a drink opening with a complete leakproof cover. Neither of them gets in the way of drinking or seeing.The heat retention is good, but like most mugs where the top metal is pressed thin with a plastic top, it will lose some heat through the top. There are some tumbler styles that are better. Cooling is less dependent on the lid, so cold drinks and ice will keep overnight.I really like the new design, and this will be my primary travel mug for a while to come.

In love with this tumbler! I use it every single day; it is the perfect travel mug. It keeps my coffee nice and hot every morning. It's so easy to carry and it's just a great looking mug. I love the silicone on the bottom because it keeps the mug from sliding. There's a thermos side and a side where you put the straw in. I don't use the straw because it doesn't go all the way to the bottom of the cup, so I always wind up having to either use a regular straw, or putting the cup directly to my mouth. What I do like abt the straw however is that it's super durable, so you don't have to worry abt it melting due to the heat in your drink. Overall I HIGHLY recommend this cup. I've received several compliments on it.

Pros: stainless steel material means it's lightweight and won't shatter when dropped like a completely ceramic product would. It has a ceramic coating to prevent coffee, etc. from being absorbed by the metal. When full, I turned this upside down and shook it and only a couple of drops of water escaped, which is very good since travel mugs usually leak. It's also very pretty! And it comes with a straw and a straw-cleaning brush, so you can use the mug for iced drinks too. Although the drinking hole is quite small, I found it adequate and not distracting to use.The mug retains heat well: after sitting full (with lid on) for 10 minutes, the temperature had dropped by only 1 degree F, and after an hour it had dropped by only 8 degrees F. After two and a half hours, the water was still warmer than room temperature.Cons: There is a sticker on the lid that says not to use with liquid hotter than 50C (122F). It's unclear whether this is because of the materials used or simply a safety warning for liability reasons. Latte milk is heated to about 155F and coffee and tea are brewed even hotter, so that's not ideal, however I find that 122 is a comfortable temperature for consuming hot beverages so although it's possible they shouldn't be brewed in this mug, it should be fine to transport them in the mug once they're ready for consumption.
