Magnet 18oz vs Devon 18oz: Which Travel Mug Is Right?

Quick answer

If you need a leak-proof, insulated mug for hot coffee on your commute, choose the Magnet 18oz stainless steel travel mug. If you prefer the clean taste of glass and mostly drink cold beverages like smoothies, the Devon 18oz glass tumbler is your pick.

Material matters: stainless steel vs glass

The biggest difference between these two Ello mugs is the material. Stainless steel is durable, lightweight, and excellent at keeping drinks hot or cold for hours. Glass offers a pure, non-porous surface that doesn't retain flavors or odors, but it's more fragile and doesn't insulate as well.

Think about where you'll use the mug most. A stainless steel travel mug can handle being tossed in a bag or dropped in a cup holder, while a glass tumbler needs a bit more care, especially when you're on the move.

Hot drinks vs cold drinks: which keeps its temperature?

If you're a coffee or tea drinker, the Magnet's vacuum insulation is a game-changer. It keeps drinks hot for up to 5 hours, so your morning brew stays warm through a long commute or a busy morning. The Devon glass tumbler isn't designed for hot drinks—it's better suited for iced beverages, smoothies, and water.

For cold drinks, the Magnet also performs well, keeping drinks cold for up to 24 hours. But the Devon's glass construction means your smoothie or iced tea won't pick up any metallic taste, which some people prefer.

Leak-proof design: a key difference for commuters

The Magnet features Ello's patented sealing slider, which is designed to be completely leak-proof and works with one hand. That's ideal if you're driving, walking, or juggling a bag and a phone. The Devon uses a friction-fit wood lid that helps prevent splashes, but it's not leak-proof—so it's better for desks, picnics, or short trips where spills are less likely.

If you plan to carry your drink in a backpack or purse, the Magnet's leak-proof guarantee is a major advantage. For a casual sip at work or home, the Devon's splash-resistant lid is sufficient.

How to choose: Magnet vs Devon

• Prioritize hot coffee on the go: Choose the Magnet 18oz travel mug. Its vacuum insulation keeps drinks hot for up to 5 hours, and the leak-proof sealing slider is perfect for commutes.
• Prefer cold drinks and pure taste: Choose the Devon 18oz glass tumbler. Glass doesn't retain flavors or odors, and the included straw makes it great for smoothies, iced tea, and water.
• Need a leak-proof seal?: The Magnet's patented sealing slider guarantees no leaks, while the Devon's friction-fit wood lid only prevents splashes—so if you're carrying it in a bag, go with the Magnet. Check the lid fit regularly on the Devon to maintain splash resistance.
