Contigo Streeterville Desk Mug Insulated Coffee Thermal Mug with Stainless Steel Handle

Product Information

Cup holder/single-brewer compatible: For those looking for compatibility with a single-cup coffee brewer, we’ve noted which mugs are seven inches or shorter (typical height for a single-cup brewer when the drip tray is removed; your machine may vary), and whether a “shorty” model (usually in 12 oz capacity) is available. The hinged-lid Thermos and Zojirushi mugs are pretty easy to clean, with the Thermos Direct Drink taking an edge here because of a vent design that’s a hole rather than a tube. Contigo is now one of the most prolific brands in the travel mug market, and the Auto-Seal Transit is the best model in their line. If you need your drink to stay hot for an entire day and you don’t want to fill a giant thermos, the Thermos – Sipp is a fantastic mini-thermos you can drink from with one hand.

Vector Files: These file types usually have .eps, .ai or .pdf at the end of their file name. Instead of using pixels, they use mathematical formulas to create shapes. This means that they can be scaled infinitely without losing quality.

Note: This is one of the more confusingly named products we researched — it’s sometimes called things like “Sipp Stainless Insulated Drink Bottle” and is nearly identical to the “Commuter Bottle.” Whatever the name, we liked it. It’s probably worth noting here: all these manufacturers specify that they use BPA-free plastics. Non-steel mugs

Bloomberg found this OXO mug quite difficult to destroy. Dropping it three times from ceiling height before giving up. We like its durability, but the push-button lid is the only one we tested that isn’t dishwasher safe, and it traps a good quantity of fluid in the spout even after it’s closed, which makes it messy to drink from. The discontinued champion: CamelBak – Forge File Types– It doesn’t have to be a specific file type at this stage, but we prefer vector .ai, .eps or .pdf files. Don’t worry if this doesn’t mean anything to you, we can work with almost any file type so just send us what you have to hand. The Bubba was included because it has the highest price to consumer rating ratio of any of the mugs we found, and the ceramic liner is a unique feature. While on the whole, this mug seems a decent value, that liner didn’t prove to be an asset in any way we could find, and the way the lid collects drips, and spreads them around is just annoying. The fact that the plastic ring which attaches the lid to the body just popped off in our eight-foot drop test makes us wonder how long it would take for grime and water to start collecting at that joint (even in normal use).

Camping

While the paint came out in our simple rinse procedure without any obvious dribbles or droplets remaining in most cases (there was a tiny drop left inside the Klean Kanteen’s three-piece seal), we did spot some residue left behind on all the mugs under a UV inspection light. After 30 minutes, 50ml of water was decanted from each mug into a 100 ml pyrex beaker every 15 minutes. With a bench thermometer and K-type probe, we took eight samples from each mug, leaving a slightly larger sample at the end. This controls for the way most of us drink away the specific heat capacity of the water in our travel mugs if we sip periodically over the course of a commute or while working at a desk.

We included a drop onto a padded surface in our leak test earlier, and all of the mugs escaped that without damage (most didn’t even leak). If you want a built-in loose-leaf-infuser option: Contigo, Thermos, Stanley, and Zojirushi all sell tea-steeping versions of the mugs we tested here (or snap-in accessories) that might help you out, but we’ve been happy with the convenience of drop-in or basket infusers.

Caffeine keeps us alert, awake, and energized. The Contigo – Transit ensures that it will also go into your mouth, not onto your lap or computer. The easy-to-sip-from self-sealing design makes it a clear winner for most uses, though it doesn’t have the best heat retention.
