Does not leak - if you attach the lid with the spout UP not down!
on 13 March 2015
This cup is leak proof if you are careful to attach the lid only with the spout in the upright position. If you have the spout down, the air in the cup cannot escape when you press the lid on, meaning the lid stays loose. So, leave spout up, press lid on until it clicks all around the edge, then fold spout down.
Also, the spout holes can be cleaned with a tint pipe cleaner or teat brush.
