Almost...
Slide in Ye Olde Fashioned Bank card with raised numbers: excellent.
Slide in modern flat credit card: amazing.
Slide in work ID: great.
Slide in state-issued driver's license: hmm. Seems sort of loose in there?
I flip the wallet slot-side down with no force, the DL *usually* stays. If I jiggle the wallet a little, not using the slider, the DL always falls at least a third of the way out. The card then pulls out very, very easily if it hasn't already gone bouncing across the table. When all the cards are inside (or any combination of those cards, or other cards I found to try, including an old paper metro card), using the slider will pop them all up, but the DL can and mostly will just slip immediately back down to the bottom. The DL only stays firmly inside if I cram this thing absolutely as full of cards as possible, which is sort of counter to the reason I got this in the first place.
Still, for almost literally every other card, including thin insurance cards and the like, it works a treat. I just shouldn't have to jury-rig some way to keep my driver's license in it. I refrained from rating the purchase lower on the off chance my state actually makes their ID cards out of Teflon and dreams and never told me.
