wooden cages/good robo cages

[taco bagel]

so rn i'm keeping taco (my robo hamster) in a kinda small bin cage and i've been wanting to upgrade so i've been looking through my options (i prefer store bought cages btw) and found this cage

http://www.amazon.co.uk/gp/slredirec...getName=sp_atf

it looks pretty good to me with the large floorspace and not too bad price (i'd still have to save but i could do it), but i have a few concerns

first of all i'm not sure if taco would be able to chew through it as it is wooden

also the height with the levels concern me, i'd be scared she'd fall and hurt herself

if anyone knows any pros or cons of this cage or any alternatives that would be appreciated!
