Love the quality and versatility of the different caps. I really love the spill guard which makes drinking hot liquids an easy

I was having trouble picking which Carter mug to purchase, I've been on something of a quest for the perfect cold travel tumbler since I've started going back to the office once a week, and having issues with the hot cups I had (they were all great, but several years old). This system fixed that. No need to be on the fence. For cold I've used it for iced coffee, iced coffee milk beverages, soda, spring water, etc. The only issue is that with carbonated beverages you have to thread the lid down VERY slowly. But that's not a true problem. For Hot I've used the Move lid with insert and the Slide lid. I prefer the slide while driving, but the move while actually on the go and not actively drinking. Perfect way to carry a hot cup of home made pour over or other to the office, keep it hot and drink it at my desk. I thought I would be unhappy with the 16oz size overall, but honestly it's been perfect. I think the 20 oz would actually have been too large. I have a 24oz Simply Modern Tumbler but the straw was cheap and I had to by more straws for it, the lid is cheap feeling plastic, like a kids knock-off of Thermos from when I was a kid in the 90's. The Carder by comparison has a much grainier texture which makes it easier to hold on to, even when wet, and a much nicer material finish on the lid, much higher quality straw, and doesn't grow comically outward like a cone as the Simply Modern does. I have read that it doesn't work with Aeropress, but have not yet used it with mine. I'll see soon. Two weeks in and I'm in love.

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

This is the only travel mug that I have ever had that seems truly leakproof. It also is ceramic which is critical as metal mugs change the taste of hot tea with milk (my beverage of choice). I am not giving it a 5 star rating as cleaning the slide lid involves taking it apart and putting it back together. Even with instructions (the video is not particularly helpful), this was a challenge the first time I tried it. I finally got it disassembled and then struggled to put it back together (use a small screwdriver, not a coin, and only turn a quarter turn). I hope future cleanings will go more smoothly or this will only be used for cold beverages.

Best travel mug, especially if you like both hot & cold drinks! The lids are also very secure, so no spills.

I love my Fellow cup/thermos. It keeps things so hot or so cold for so long.

Spot on like the other bottles. Spill proof and just easy to interchange

I’ve been looking for a cup that keeps my coffee not just warm but HOT for so long and have had no success. This cup does just that and I’ll never switch from Fellow. 10/10 cup!

Beautiful design, fits in the cupholder, great find

Love it! Super cute, the only thing I wish was that the wording could be a bit bigger! Not something that surprised me though as the proof was exactly like what showed up!

The slide lid feels, crunchy/clunky every time I use it I feel like I'm going to break it

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 was looking for a cup for water that was ceramic inside. I live in FL, and water is a must, everywhere I go. My daughter told me about the 12 ounce cup, and I've owned that one for a year or so. but it's not big enough for a couple hours worth of water. I like the system, and it's flexibility. I get tired of drinking water that tastes like stainless steel. I'm very pleased with this purchase!

I highly recommend the Carter 3-in-1 System Coffee Mug for its innovation, durability, and stylish design.

Best travel mug ever. Doesn’t leak! I love having the different lids.

Enjoying having three options in one cup. The sip guard is a great addition and it’s nice how firmly the straw fits in the lid to prevent spills or a rattling noise when on the move. It’s still a little too big for the cup holder in my car which is a bummer, but aside from that, no complaints!

Was purchased for a Christmas Gift. I had originally purchased a slide lid coffee mug from Black Rifle Coffee Company (BRCC), with their logo branded on it (manufactured by Fellow). I use the thermos often, throw in the dishwasher and abuse it daily as I work in the trades. This thermos mug does not leak, easy to drink from, easy to clean and maintain. I now wish, when I purchased mine from BRCC, that it came with the interchangeable lids; but I am glad that when purchasing this gift set that I can purchase a single replacement lid. Great product.

I absolutely love the sip system but I have found that it holds onto smells really easily. All of the lids are great but the slider lid is difficult to clean.

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.

Great Product! I purchased this as a gift for my husband. He wanted something that would keep his coffee hot for a long time. He was very pleased with the results. Nice sleek look too.
