Customers find the coffee mug keeps drinks hot and appreciate its 24 oz capacity.

Keeps my coffee hot!

ReenieOctober 1, 2025

This coffee mug is just perfect for me! The seller added an extra rubber ring and a brush to clean it with and cute little coffee stickers with an instruction book. I was amazed how much thought was put into it. The mug holds 24 oz and keeps my coffee nice and hot. It can be a bit heavy if you have arthritic hands. The lid fits on extremely tight so no worries about spilling anything. Would highly recommend buying it from this seller! Read more

An Ode to a Mug

Rich O.January 7, 2026

A truly wondrous chalice that preserves the heat of my morning brew for many a long hour, as if the very sun were trapped within its walls. For those who seek but a single, modest draught and naught more, its proportions are truly most exquisite. Yet, I must confess, the lid doth cling to the rim with a stubborn tenacity, yielding only to a most determined hand. Perchance, as the seasons turn and use wears down its pride, it shall learn a more gentle obedience. Read more

Works well. Lid is almost impossible to remove.

A. BairdJanuary 12, 2026

The mug is well built and keeps the coffee warm very well. My only complaint is that the lid fits so tightly that it’s almost impossible to get off. My husband can’t remove it at all and I have a difficult time as well. Read more

Fits under my single cup coffee maker!

Forest DebDecember 22, 2025

I wanted a 24 ounce mug but it had to be short enough to fit under my single cup coffee maker. That is harder than it sounds since most are made tall and skinny at the bottom to fit in cup holders. This 24 oz mug fits my coffee maker perfectly, is really well made with a good non-leak top and an extra gasket. I am very impressed! Read more

A mug that keeps coffee hot with a lid that doesnt leak.

Johnny R VarneyJanuary 9, 2026

Works great, lid can be difficult to get off but I've been through a few that leak very badly so I prefer this one. The coffee stays hot for awhile I can only attest for 35 minutes because that's as long as a cup has lasted. The mug is a contradiction, the outside gets ice cold ( when outside in the cold ) yet open the the cup for a drink and hot steaming coffee is inside. It comes with a small cleaning brush and an extra lid gasket. My only complaint and its not fair is 24 oz is really pushing capacity right to the too without the lid, I expected 24 oz to be at the bottom of the lid. It works great, keeps coffee hot for a long time and doesnt leak. Read more

Decent, but pros and cons

Rich N.October 10, 2025

For the price- ok... this 12oz mug performs ok. I have included a very brief list of pros/cons below for consideration. In fairness, my review is based on first-hand (pun intended) experience with Yeti's 10oz Rambler mug (linked below). You can do your own value math since the Yeti is the twice the cost of the RAYMYLO, but the Yeti keeps hot drinks way hotter, way longer PERIOD. If you're a slow sipper, the Yeti might be worth the extra $$$. If you gulp and want to save a little- go for the RAYMLO. Pros: - 12oz. capacity versus some competitors' 10oz. - It looks great! The indigo to black ombre look is really nice- exactly as pictured on the storefront (thus no customer picture!). - The lid fits very tightly and the assembly seals beautifully Cons: - Handle is a little thin and not terribly comfortable in hand - It just doesn't keep liquids hot as long as expected Read more
