I have two beakers and have used them alternately nearly every day for 3 months. Contrary to the other reviewer, mine have never leaked and the size is critical if you have a thirsty baby like I do. HOWEVER the design is stuck on and after 2 months starts pealing off and the tube at the top is marked from where my 18month old likes to grip it with his teeth... so I would say fab but not for heavy use! (Perhaps better if not washed in the dishwasher - but who has the time!)

I now only use this product around the house with water as it is pretty big and chunky - certainly not a pop in your handbag beaker.
Its not entirely sealed either so leaks a bit.
My toddler was a bit frustrated when I tried to give him his nighttime milk in it as he had to keep stopping to let air in.
