A general question about the OVO cages for hamsters?

I have two ovo pads connected with the adventure pack, and a single Russian Dwarf hamster living in there. The tubes when connected properly are escape proof, you don't have to worry about that. I find it perfectly simple to clean, not as easy as just emptying something into a bin, but it's not difficult. Scoop out the stuff from the pads, take the connectors apart and clean, dry, and put back together. As far as ventilation goes my hamster lives happily, there's never been any condensation or anything like that, the cage never seems to be lacking in air. The tubes are too big for my hamster to climb up if they're vertical, so as far as size goes as long as your Syrian isn't really fat then they should be the correct size. Because Syrians are bigger I'd say that a minimum purchase would be the ovo loft (the bigger tank like part), the ovo pad and the adventure pack (you buy those together as the suite). The stairs to the food bowl can be a little difficult to climb, but providing a little wooden ladder or hollow log to climb through sorts that out, else just add a small separate ball. I also blocked the hidey hole under the wheel and provided another house because it's hard to get your hammy out for cage cleaning.I've kept a Syrian in a Ferplast Mini Duna before, that's really easy to clean, is just about the right size for a Syrian and the only bars are at the top, which is out of reach to the hamsters as long they've got nothing to climb on right below them.
