It's definitely good for pokéballs! But it also bothers me when my bag is full I have to keep throwing away so many items. One of my friends had an option he could turn on to open gifts even when the item bag is full, but that option doesn't show up for me! Earlier this week he did say the option disappeared for him again x/ I might open them more often if I could have that option so I don't have to throw away items every 2 gifts xD
