Product flaws but good product to get rid of seeds

I love the product in general but it had a couple of flaws. First the top that screws down, the plunger sticks so bad that I have to get a screw driver under it to lift the top cap off. The part that you drink out of. Second you can't shake the bottle without it leaking. And the top gets super messy because it holds all the smoothie while you turn it. And finally you can't put apples or fruit in it and drink out of it with the lid closed it won't plunge down. Maybe it's not supposed to be closed.
