GUDEMAO 20 oz Insulated Coffee Mug with Ceramic Coating Stainless Steel Travel Mug Tumbler with Handle Lid and

It is a great cup (20oz). I have used it for the past 4 months. I could give it just a 4 stars because I can not clean the lid easily and it is a bit of a sippy style, but I do not always use the lid and it is reliably tight. I have not had any leak issues. So I am very pleased about its capability of keeping my drink warm long enough compare to other alternatives, hence the 5 stars. I do though have the habit of heating all my cups with hot water before I pour coffee I them. This one takes good advantage of it compare to others that do not retain heat as well. The handle is a good size, but I wish it had rounder edges. This cup travels well in my car cup holder. The cup has good heat retention and it makes it … flavor retention, I guess… You need to use soap to clean it between coffee and tea usages. It is the cup I use the most. Read more

Love their cups. The ceramic coating makes for a great tasting drink. Drink kept hot for hours!! Read more

Love the porcelain lining, the size and the color. It doesn't leak. I have ice water in it now and will see how long it remains cold. It has a very metallic sound to it and there is no non skid grip type coating or anything on the bottom so when you set it down it clangs if you aren't very careful. You'd definitely be noticed in a meeting. My favorite porcelain tumblers that have a thicker, heavy duty coating on the tumbler and some sort of rubber non skid circle on the bottom, but they don't make the 20oz with a handle that is shaped like this. This cup would be perfect if it had a heavier coating on the outside. Read more

Nice and durable, just don’t bang the insides with metal objects , I use a milk frother to stir my coffee, works great as long as I keep it away from the sides. It will make tiny scratches on the ceramic if it makes too much contact. My cups are in darn near new shape still. I’m happy with this travel mug. Use them daily Read more

My product arrived quickly and had everything with it that was advertised. I felt like it was a good price. I love the looks of the product. It's sturdy and seems to be well made; however, I am very disappointed in the quality of performance. The description stated that it kept hot beverages hot for up to 8 hours. My coffee doesn't even stay warm for 4 hours. It is cold before the 4 hour mark. Read more

love this cup. keeps water cold good quality. I use a walker and I need to hang my water glass on it, but the handle design is closed, so I can't do that. That is a me problem, but the cup is very good. Read more

I thought I was buying a travel mug, not entering into a committed relationship with a tiny thermal tyrant. This little ceramic-lined dictator looked innocent enough when I unboxed it, small, cute, just the right size for my ancient Saturn’s cup holders (circa 2004, when cup holders were apparently designed for shot glasses). My first mistake? Thinking I could outsmart a mug. I did my usual morning routine: fill with boiling water, go about my business, dump the water, make tea, and head out. THREE MILES into my commute, I go for that first glorious sip and HOLY MOTHER OF EARL GREY this thing was hotter than the surface of Mercury! I'm pretty sure I saw my reflection in the liquid lava that was supposed to be my breakfast beverage. Twenty minutes later (still driving, still optimistic), I tried again. Nope. Still molten. At this point, I'm wondering if this mug has a built-in nuclear reactor. I get to work as a nanny, and little miss immediately wants to investigate this mysterious lidded contraption. "Can I take the lid off?" she asks sweetly. ABSOLUTELY NOT, child, unless you want to witness your nanny spontaneously combust from drinking liquid fire. We head out for a walk. I'm sneaking sips like I'm trying to taste-test the sun. Ninety minutes in, I'm having a full breakdown because I just want to drink my TEA! In a moment of pure desperation, I ripped off the lid like I was defusing a bomb. Five minutes later, yes FIVE MINUTES I could finally consume something that was merely "surface-of-a-pizza-straight-from-the-oven" hot instead of "molten-core-of-the-earth" hot. The safety test? Little miss couldn't figure out how to remove the lid, so if your tiny humans manage to steal your drink, they're protected from third-degree burns. It's like child-proofing, but for beverages that could power a small spacecraft. A few days later, I got wise. No preheating. Left home at 11:30 AM, finished my tea at 1:30 PM. TWO HOURS. This mug doesn't just keep drinks hot, it keeps them in a perpetual state of "please don't sue us if you burn your tongue off." Fair warning: this mug is so lightweight that you might accidentally launch it into orbit if you lift it too enthusiastically. I nearly gave myself a black eye trying to take a sip. It's like holding a feather filled with the wrath of a thousand suns. Bottom line: If you enjoy playing Russian roulette with your taste buds, if you want a beverage that stays hotter than a fresh asphalt road in August, and if you're looking for the Holy Grail of "Where did I put my coffee?" moments (spoiler: it's still hot after three hours), then congratulations, you've found your thermal soulmate. Just remember: this isn't just a mug, it's a commitment. A hot, scalding, wonderfully frustrating commitment. Cheers to my fellow mug survivors who have also purchased this little thermal overachiever, may your patience be strong and your tongue burns be minimal! Read more

Lid raises off if contents are hot. if turned over, comes off quickly. Handle uncomfortable to use as well- edges not rounded. Read more
