Not so good!

This is the poorest example of a ninja product I've ever seen. I own several ninja appliances and just love them, so I thought this cup would be a dream come true. Unfortunately it's a nightmare. It doesn't work any better than a cup costing a third of the price and it leaks like a sieve. I'm an engineer and I understand how a gasket works. I removed the gaskets and thoroughly cleaned both the gaskets and the seats. I made sure they were replaced properly and it still leaks. The cup itself seems to be well made but the lid leaks, sprays out a mist when you first open it, it is difficult to clean, and I'm guessing it would be very easy to lose the gaskets making the cup useless. The ninja sip perfect 16 oz travel mug does not live up to what I expect out of a Ninja product.
No, I would not recommend this to a friend.
