You’ll really enjoy having the 3in1 ! The only reason I have it a 4 star is because of the slide lid . Both my husbands and mine cracked in the slide tracks . We hardly used . Purchased in October . Maybe the batch was bad or they need to rethink the design. I really like FELLOW . Their costumer service is wonderful . They sent us replacements.

I love the quality! Even with the straw lid, it’s slow to spill when turned over. Keeps my drink cold; living in San Antonio and leaving a drink in the car, you can expect a warm drink upon return. I’ve not found that to be true (so far). Great for the gym, traveling…love it

Definitely flavors hot coffee. Yes, the cup also keeps coffee warm, but so does every modern travel cup. The flavoring of the coffee isn't as extreme as Yeti, which basically renders hot coffee undrinkable, but it still definitely adds a bitter, metallic taste.

I already had a Fellow kettle and love it so I bought the Carter. It is clearly a solid product but not what I expected. The size is awkward, it barely fits in the cup holder in my car and doesn't sit easily in your hand when carrying it. The mouth opening is an odd size, not easy to clean or put mix a drink in. Also, its pretty heavy so I thought it would keep the drinks warm and cold a long time but it doesn't. I would return it if I could. Wouldn't recommend.
I love Fellow’s thermoses. I had been on the hunt for a long time for something that was easy to clean—no more gross mildew/mold in places I can’t reach—and was leak proof. This thermos does both AND has a ceramic coating inside to prevent a metallic flavor. This isn’t even a detail I thought would affect my experience, but it does!! And these are also some of the coolest looking thermoses ever. Pricey? Sure, but so worth it if you’re a one and done kind of person like I’ve tried to be.
I was looking for one mug/cup for my coffee and water throughout the day, and having the different lids (cold, move, & slide) really make it worth it for me. The cherry on top is the shape of the lip, it’s comfortable to drink from without a lid on. I’m a fan of the flared straw, it stays in place. Another thing I like is the size and shape. It’s not bulky or top-heavy like most travel mugs.
The new (?) slide lid is a revelation. SO much better than the old version which was at times hard to control or would surprise you with an excess of liquid. It also, understandably leaked. AND the new one is considerably better at maintaining heat. That's important in the Sierra in the winter or when in a cold car in the AM.
Like the variety of lids. The splash guard one and the quick sip after both leak-proof, haven't tested the cold one yet. Worth nothing the 16 oz lids are compatible with the 12 oz tumbler as well and I assume with the larger. Sleek design, feels good in your hand, looks and feels premium. But I'm still not sure I'd buy it full price. I got this set 30% off and I'm happy with that price.
I’ve never been this excited about an insulated cup. This is one of the best designed products I’ve ever used. Every detail from the drinking experience to the packaging is extremely well thought out and useful. I love that it has several lids so I can use my cup for whatever I’m drinking that day. It’s perfect for drinking at home or on the go. I plan to replace all of my travel mugs with this one.
I have mostly used the “slide” top and while I did read some issues in other reviews, my experience has been absolutely great so far. I will add that the travel mug sits mostly upright at all times (in my bag, car, etc), so I can’t speak to how it would do lying on its side. However, the few times I’ve tested it, and vigorously shaken it, I have had zero issues.It is sleek, elegant, minimalistic, and functional. I love it.Would be cool if you could personalize it (engraving and such), but that wasn’t an option at the time of purchase.
