Reviewers love the Contigo Autoseal West Loop Travel Mug for its user-friendly design, including an easy-to-grip body and a one-hand, push-button spout. The mug fits well in cup holders and is reasonably leak-proof, experts say. However, it doesn't keep drinks hot or cold quite as long as some competing travel mugs, and many reviewers say the mug's plastic lid isn't as durable as its stainless-steel body.
Solid marks for temperature retention. Contigo says the Autoseal West Loop Travel Mug keeps drinks hot for four to six hours and cold for 12 to 18 hours -- claims owners back up with solid reviews. Experts give the mug just average marks for temperature retention, saying it kept coffee more than lukewarm for only up to two hours. Designed to seal automatically between sips, the mug fares well in experts' leak tests. While a few owners report leaks and condensation, most say they haven't had any trouble. However, some reviewers note that the mug lacks a secondary lock -- to keep the lid from opening in a bag, for instance. Others complain that the mug imparts a metallic or plastic taste to their drinks. The mug is available in 16- and 20-ounce sizes.
The 'most convenient' travel mug. Experts dub the Contigo Autoseal West Loop the "most convenient" travel mug, praising its easy-to-hold, one-hand design. The mug also fits more securely than others in most cup holders, they say. Owners also like the push-button operation, saying the mug is easy and comfortable to drink from on the go. A few say the mug's design makes it hard to sip a very hot drink, however. The plastic top is dishwasher-safe and has been redesigned for easier cleaning after complaints of foul odors and gunk buildup plagued a previous model. The mug's stainless-steel body is not microwave- or dishwasher-safe, and it does not have a carry handle.
Plastic top may be flimsy. Many owners say the Contigo Autoseal West Loop Travel Mug stands the test of time, with some saying they've used it for a few years with no issues. However, several say the plastic top breaks too easily, and the lid didn't survive a fall from a moving car in expert tests. Replacement lids (Est. $5) are available on the company's website. Some other reviewers complain of dents and dings. Contigo backs the mug with a limited lifetime warranty.
Reviewers say the Contigo Autoseal West Loop Travel Mug is good for on-the-go drinking, with an easy-to-hold, one-hand design that fits securely in a cup holder. However, it didn't retain heat as well as some competitors, keeping coffee more than lukewarm for no more than two hours.

Editors like the Contigo Autoseal West Loop's one-hand, push-button operation. They also say the mug provides a leak-proof seal. However, the mug is tall and narrow, making cleaning tricky without a bottle brush, they report.

The Contigo Autoseal West Loop fares well in shake and drop tests, staying leak-free, but its plastic lid broke during a fall from a moving car. But the mug earns praise for its easy push-button design and heat retention, making it the "most convenient" of six tested travel mugs.
