When I first got this, I liked it, but didn't love it.  I found that changing the infuser and the sipping cup and then having the outer lid seemed to be too fussy.  Plus, the design of the lids didn't please my eyes.

But using it for a few weeks, I love it.  I love that the lids actually remind me of the old SLR lenses and the attachments to them.  I love that its the perfect size to drink out of and I love that its ergonomic feeling to it.

The tumbler also has a good weight to it, not too heavy or not too flimsy.  While I don't like plastic pieces, the lids are seemingly made using better plastic.

The only negative I have is that it doesn't keep liquids at hot as the Thermos commuter tumbler (the infuser is rated 6 hours Hot and the commuter is rated 8 hours Hot).  But for my purposes, it remains WAY too hot for more time than I need it.

Overall, for the price, just get it.  I use it for tea in the morning and then wash it so I can drink water the rest of the day.  I never use my sigg bottle anymore (plus Siggs are a pain to clean)
