Query: Poor design dont be decieved by looks

I bought this for my 7 month old as I liked avent pacis. Looking outside it looked like the best buy among all other brands as it had a lid and also measurements in oz and ml on the side both great features missing in other brands. But the problem with this is it is very tough for baby to get any liquid out. I spent more time trying to figure out if my baby was getting anything in his mouth at all. As another reviewer mentioned this cup is sip proof too!!!
