This is a great thermos. I haven't had any leaks and my son takes this to school with him everyday. We even lay the thermos on it's side to fit in his lunch box. The thermos is great quality. I am tempted to get more for my other son. These same thermos are available at the big box stores for a little cheaper.
Edit 10/22/2012:
I bought one first to see how I would like it. I have 4 of these now because they work so well. They are great for what I need-- a kindergartner and 4 year old who takes their lunch, and a 1.5 year old that won't drink out of a sippy cup. I have to warn of three potential leakage points:
1. I've noticed that the top has to be just in the right position to screw onto the thermos so that when you tighten it, the top actually reaches and tightens down to the yellow ring you see on the thermos. If your top does not completely touch the yellow ring all the way around the thermos, you risk a leak.
2. When you open the lid, you will see a silicone(?) triangular shape. In the shape, there is a small hole that allows the air pressure inside the thermos match the outside air pressure for easy drinking through the straw. Below the hole is the mouth piece which is the 'top' of the straw. You insert the harder tubular straw into the underside of the mouth piece and thus under the top. The hole is there by design, but that also means, if your child doesn't snap the lid shut or sets the thermos on its side while half full (or more) with liquid, then liquid will leak out from the hole. If your child does this, you should buy a sippy cup that is leak proof when you tilt the cup.
3. The silicone mouth piece and the stiffer straight tube are completely removable from each other. The mouth piece is even removable from the top. Please remove the mouth piece from the top to clean and from the tube to get all the liquids out and avoid mold and other smells. Just be aware that when you pull the mouth piece back through the top to put it back together, you have to get that triangular shape of the silicone to cover the triangular hole in the top completely. If you don't, then it will leak even if you have snapped the lid closed.
I would still buy these again. Any leakage issues are user error. I really think this is easy to use, easy to disassemble for cleaning, and easy to clean. This keeps my children's drink cool even 9 hours later.
