Most problems with mugs I have tried in the past are solved in this product. This mug comes with a tight sealing lid so that you can put this mug with hot drink in a brief case upside down and run to a subway station. No spilling, and this product is better than a plain Saran Wrap solution. The sipping lid has a deeply recessed bottom where you have a hole for liquid to come out. That is, the spill risk is very low even in pitching and rolling Boston''s subway. So, you rarely need to use the sealing lid unless you want to brew tea in it or put the mug in a backpack. (See the other review to learn how to brew tea in it.) Also because of this deeply recessed sipping lid, this mug is easier to use spill-free while laying on a sofa or maybe even on a bed with a high pillow!

Lack of handle presents little inconvenience at any situation I''ve used this mug. A both handed person like myself needs not worry which way to put the mug, which way to put the sipping lid, and which hand to hold the mug. It''s very left hand friendly, more so than having two landles on each side.

If criticism is an obligatory part of the reiview, I offer a few. This mug''s tea leaf strainer is given enough space for most loose teas, but it is not enough for some herbal infusions, particularly whole dried preparation of chamomile flower. This mug''s advertised capacity is 11 ounces, but the line specifying the maximum fluid level is actually 275ml (10 ounces). I wonder if they could make it a bit taller for increased true drink capacity and enough space for chamomile to expand. The leakproof lids depend on silicon gaskets thus they should not be cleaned in a dishwasher, a convenience requirement.

Overall, this mug is slim, tall, leakproof, beautiful design, and very functional and compact. The quality of tea made in this mug is as good as ones made in tea pot as long as the leaf is of good quality (sentimental value not included). The diameter of the mug at its widest (around lid) is only 75mm (3in) so it will fit in most briefcases together with a book and couple manila folders. I just wish it was 8.5in tall and 350ml capacity. Unlike so many poorly designed products, you know this one was designed by designers and engineers who love tea and coffee.

I wrote this original review quite some time ago, but I thought to add that I now own three of this product, and I still use this product daily (home, office, travel) and I still think this mug is totally awesome for people who appreciate high quality tea. STILL HIGHLY RECOMMENDED in 2010.

Addendum May 2011.

Most common question I get is how best to clean the inside of the tea mug when it gets all browned. The answer: fill the tea mug with hot tap water, dissolve a teaspoon full of oxygen bleach powder (sodium percarbonate aka Oxyclean), attach the lid and the cap, gently shake a few times, and loosen the cap immediately. Leave it in the sink for 10 to 20 minutes. Make sure the lid is attached loosely, and never tightly. Dump the stuff, rinse it with water, and you''re done. Chlorine bleach (Chlorox) will do the job just as well, but you''ll have to deal with the bleach odor for a few days. Oxygen bleach leaves no odor, but it forms oxygen gas, which builds up the pressure inside and explode the lid, if left attached tightly (I''ve done that!). That''s why I emphasized to loosen the lid when leaving it in the sink.

This is how you brew tea:

(1) Remove outer cap and tea filter.

(2) Check all gaskets are properly seated.

(3) Twist tea filter onto the cup to seat tightly. Put tea leaves in the tea filter. Be sure the tea filter is seated correctly. You can also put tea leaves directly into your cup if that is your preference.

(4) Pour hot water up to middle of filter. Over fill may scald.

(5) Properly seal the outer cap tightly to prevent leaking when used for travel. Turn upside down for quick brew.

(6) Remove outer cap and tea filter after brewing and replace with slipping lid.

For Best Results

For maximum insulation efficiency: preheat or precool your cup just prior to use, fill with hot or cold tap water, let stand for 5 to 10 minutes and empty.

Note that it comes with 3 lids: (1) Outer Cap (2) Tea Filter and (3) Sipping Lid.

I love this thing. I''m in grad school, on campus from 9am-11pm every day but Saturday, and this traveler is perfect. Instead of repeating all the other glowing reviews, I''ll just add a few things others missed. In addition to its unmatched insulation abilities, the vacuum seal provides another benefit, and that is that it maximizes interior space. Other types of insulation require thick walls to insulate the contents, but with vacuum sealed steel construction, the insulating steel sandwich can be very thin, making the volume of the inside layer nearly equal to volume of the outside layer. It''s a small thermos that carries quite a bit of fluid.

One other thing to clarify is that this is not exactly a no-spill container. There are three tops: an inner top that is completely open but for a metal strainer/filter, an inner top that is covered but with a small drink hole in the cover, and an outer top that screws onto both of the previous and completely seals the cup. With the outer top on, the vessel is spill-proof. I carry it in my bookbag all day with nary a spill. But take the outer top off, which is necessary to actually drink out of it, and if you accidentally tip the cup over, liquid will spill out, even out of the sipping hole in the covered inner top. There is no button to push that opens and closes the sip-hole on the covered inner top, like for example on those plastic Starbucks coffee cups. However, the sip hole is recessed about 1 inch below the rim, so while it is not spill-proof, it is certainly splash-proof.

Excellent product, I might order a few more, for posterity.

When I bought this mug about 6 years ago, I paid $30 for it. I almost walked away from it b/c it was $30, but a friend of mine asked, "How often do you drink coffee?" "Uhm, every day." "And how often do you spill it?" "Uhm, almost every day." This is seriously the best purchase I''ve ever made. I''ve left the mug in my bag for 6 or 7 hours and opened it to find hot coffee and no leaks... You can literally throw this mug upside down in your bag and it will not leak. Buy it if you drink coffee.

This little tea tumbler keeps the tea very very hot. Kept the tea steaming hot for 2 hours. I eventually had to put cold water in to cool off the tea so I would stop burning my tongue.

Once the tea was cool enough to drink, the problem was the awful plastic taste I got with the tea. I purchased this product because it was stainless steel. I didn''t think about the plastic drinking piece. I used it once, tasted the plastic, and couldn''t even finish the tea. Unfortunately the entire thing is headed for the garbage.
