$ave your ca$h and buy a bigger mug without the tea brewerJan 15, 2004

First off, I agree with all the comments about the mug's nice ergonomic shape, its ability to keep drinks piping hot for hours, and its spill-proof-ness.

But, the title of my review says it all - instead of paying thirty dollars for an 11-oz mug, why not get an 18-oz mug for twenty five (or even a 14-oz for twenty bucks)? All are made by Nissan, with the same durability, ability to retain heat, and good looks. The difference in this mug is the third basket, the tea brewer, which has a mesh that is WAAAAY too coarse. This is a serious problem, since I absolutely detest leaves and other remnants in my tea when I drink it. Herbal or spiced teas (e.g. Chai) are out of the question, and even a basic large-leaf tea like Darjeeling escapes through the mesh (and also gets stuck in it, which makes it a pain to clean).

Instead, I would suggest buying Nissan's larger 18-oz (or 14-oz) mug, and with the five (or ten) bucks you save, purchase a fine-mesh brew basket, available on amazon.com (ASIN# B0000CFLAP). Remember, you have to remove the built-in brew basket from this mug to fit the sipping lid, so there's no extra effort in removing a fine-mesh, easily washable brew basket instead.

ditto the 5-star reviewsSep 16, 2003
By Byron
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.
