SUNWILL Insulated Coffee Mug with Lid, Travel Tumbler with Handle, 14oz Stainless Steel Cup for Camping, Office, Home, Powder Coated Navy Blue

This is a good insulated mug at about a third of the cost of the more popular name brands. I need a mug for camping and a multi day trip to the boundary waters canoe area in N. Minnesota. I have just started using it. It seems sturdily built and keeps coffee or tea hot for a good amount of time while the outside of the mug remains cool. I had been using a mug warmer but this is a good alternative. It is relatively easy to remove the sliding cover and the lid as well as the silicone gasket for cleaning. It is easy to add liquids and seal the mug with the lid. The one drawback is that it is not spill proof. If the mug tips over even with the lid closed, liquid will leak out, albeit slowly. I don't see that as being a problem for my use. Overall, I am very happy with my purchase and especially the price.

Excellent cup and the perfect size for the Large setting on your K Cup coffee maker. The insulation factor is superb. I judge the thermal retention by whether or not I can feel heat loss by touching the outside of the cup. With a fresh cup of hot coffee, the outside of the cup remains cool to the touch.Also, if you go for a black or white color, it is significantly less expensive than the more stylish colors.

I'm a senior with arthritic hands, and using my old favorite Contigo has become increasingly difficult. It is just too painful to either flip the top or press to open to drink. THIS SUNWILL MUG IS PERFECT. It keeps my coffee hot just as well as my old favorite but the slide feature on the lid is so easy to operate. While it's not totally leak-proof (by design), it would be very difficult to knock this over because it's low design is shaped like a mug, not a tumbler. I love the handle, which makes the mug so easy to pick up and drink from. 5 stars all the way.

Great mug, good size, keeps drinks hot or cold for hours. Easily cleaned. Lid is pretty good, and doesnt leak....but i swapped it out for my yeti lid which makes this mug even better

So glad I read previous reviews, so I know to remove the ring in the lid to wash separately. The lid works perfectly.Love this mug; it's perfect for morning coffee or afternoon tea. I was getting sick of my hot liquids getting cold. Haven't tried ice but that's coming.Stable and keeps stuff hot; perfection!

I have a tendency to carry my coffee around in the morning instead of sitting at the kitchen table, so I need something with a lid. This is perfect - the lid is very secure, keeps coffee hot for a long time.

Excellent value. Keeps coffee hot for 4-5 hours. Lid fits snugly. The lid does have a steam/pressure release hole, so not completely leak proof.

It's a pretty color and it keeps hot liquid hot and cold liquid cold the way it says it would. However it also says spill proof which it is not if it has liquid and you turn it to the side it definitely leaks. Too bad other than that it's a nice cup.
