DOWAN Coffee Mugs, 15 oz Mug Set of 2, Large Ceramic Coffee Mug with Cork Bottom and Spill Proof Lid for Mom Dad, Big Mug for Latte Tea, Matte Grey

Very nice mugs. They keep coffee hot, thanks to a small plastic top that slide open so you can drink what's inside.

I got these for a white elephant gift and they were fought after. They are stylish little mugs with nice sealing lids. The bottom coaster is cool and magnets on so you can simply remove it when tossing it in the dishwasher. I know the person that ended up with these and I often use em when visiting and know that they appreciate them too.

These are good quality mugs with a weighty feel and secure lid.The only point of concern was that the metal coin on the bottom of both mugs (these are the attach points for the magnetic cork base) were detached and I had to resecure them with superglue. The factory adhesive was obviously of poor quality so I would encourage anyone who buys these mugs to check the metal coin on the base of each mug and make sure it's solidly locked in place. If loose, they may come off during washing and if one fell down into a garbage disposal you will not have a good time picking it out.

Second update:I received 4 replacement mugs, and so far none have cracked or chipped. They hold heat well, and the lids that came with them fit better than the previous ones. Very satisfied with the new mugs, and with the excellent customer service.Update:After writing my initial review, the company reached out and offered me either a refund or replacement of the item. They were very friendly and considerate. I never expected anything, just wanted to review the mugs. I will update again when I get the replacements.Doesn’t keep coffee warm. The 2nd day we had these, one of the handles cracked. The metal piece on the bottom of 2 fell off, and the others get rusty. Also smaller than I thought they would be. I only bought them because they were domino some really nice ones we had bought before, but those are no longer available. Lids do not fit well, either.

I bought these mugs so my husband and I would have something to put our tea/coffee in for our commute to work. Neither of us like drinking from plastic or metal travel mugs very much, and my husband dislikes travel mugs that keep his drink really hot. Before buying them, I even went and measured the car and truck cup holders to be certain that they would fit.The first thing I noticed when I opened the package was that they are not a true white. It's not a big deal to us, but if you're looking for white, just know that these are more of a cream or very light beige.The next thing we both noticed the first time we used them, was that the lid had a really really strong chemical smell. It was strong enough that my husband just took the lid off to drink his tea. I was not impressed, but I decided to wait and see if the smell would fade. Now, after about a week, it has faded some, but it's still there enough that taking that last sip of coffee feels kind of chemically and it really isn't a good way to end the cup. I don't like this at all.The next thing that we noticed is that the mugs hardly fit into our cup holders. Instead of being 3 inches in diameter like the product pictures show, it's more like 3 1/4 inches. The cork bottom narrows somewhat, and that's the only way it can sort of fit our cup holders. I was disappointed about that, but thought I could live with it.The last straw and the reason I sat down just now to write this review is that, as you can see in the picture, the cork bottom just came off of one of the mugs this afternoon. I don't know how it came off because we've been careful with them, haven't dropped them, etc. But yeah, its off, and I can't even figure out where it disappeared to, otherwise maybe I'd glue it back on.I really am disappointed because I never spend this much on mugs. I was definitely hoping they'd be worth the money!UPDATE:A day or two after writing this review, the cork came off the second mug, and the lid on one of them started not staying down all the way when pushed into place. I should add also that we wash these by hand since we don't have a dishwasher, so they've definitely not gotten rough treatment.I started a return and ordered replacements, hoping that these were just a bad set or something. However, when they got here Saturday, I decided to return them too since the lids also smelled strongly of chemicals and the one lid already wouldn't stay completely down.

The mugs look good but function only marginally better at retaining heat than an everyday ceramic mug. The lid and cork coaster *probably* do slow some heat loss but don't expect to notice much. The heat radiating from the remainder of the mug overwhelms any advantage of these features. In short, these are not insulated to any meaningful degree. Your coffee or tea will still get as cold as fast as before. Also, the cork coaster adheres to the mug by a magnet affixed to the coaster and a metal slug affixed to the bottom of the mug. On both my cups, the slugs have fallen off, which required my having to glue them back on. I suspect the reason this happens is because heat from the cup undermines the integrity of whatever adhesive they use to attach the slug to the mug. I used a high heat tolerant superglue to reattach the slugs, which seems to have fixed what is essentially an aesthetic problem. Rated 3 star for average quality and function. It's no better or worse than that promotional coffee mug you won as a door prize at your company's most recent teambuilding training.
