Replace that bridge in the middle,it really isn't safe for so many reasons
The gaps are a huge risk for falling,and the chain is a very big risk for tiny hamster toes and claws to get caught in and therefore could cause some very painful injuries.The rope bits are most likely cotton and therefore unsafe as if they're ingested they cannot be properly digested and will cause an intestinal blockage(which can at worst lead to death if not given proper treatment which will be quite costly and stressful).
I'd get an upright wheel as well,since flying saucer type wheels just don't allow for a natural running position.They cause side arching as well,whereas an appropriately sized upright wheel would always allow for a natural and straight running position.Ideally you'd be getting the Silent Runner(not Spinner,as Silent Spinners are just not worth buying due to being terrible quality and rarely if ever spinning properly,and keep in mind that no other wheel is as safe as the Silent Runner plus despite being an investment they last a very long time and could last several hamsters).
