Flip top gets in the way of the handle viceversa. I cant walk and just tale a sip from time to time. Filter works great, but is at the bottom of the cup? Every time i take the lid off i have to be careful to not let the entire straw and filter come off because of the bottom heavy design. Why not connect this filter to the top of the lid inside the cup and have the straw after? Overall keeping it but its a bit of an over engeneered design.
