This mug is really sleek looking and feeling. There's a locking feature, so it doesn't accidentally open up. The spout is easy to drink from and the whole thing is very easy to clean. My drink stayed cold for a while. The one thing that bothered me is that it was too tall for the drink holder in my car. I would need to order a size down for it to fit in drink holder. Luckily, since it doesn't leak, I just laid it sideways on passenger seat without fear of it leaking.
