I use this cage for my Syrian and she loves it. She's incredibly hyperactive even by hamster standards and she doesn't find it stifling. It's so big and it gives me the room to put tonnes of toys there. Right now she has a suspended bridge, ladders, a see-saw, a platform thingy, lots of chew toys and a silent spinner. I usually let her out everynight. Sometimes for an hour, sometimes 20 minutes. It's a great little cage for a Syrian - mine is really happy in there.
