I did, for both my hamsters. One had the blue Savic one that's curved, the other had the green one. Once they were potty trained and got use to using litter/sand, I switched them to larger plastic containers (one ice-cream tub and one tupperware). Good thing is that now they're used to it, they'll pee in the containers even if they don't fit into the corner exactly. It's very handy as I only need to change the potty every couple of days and the cage remains fairly clean with spot cleans.
