30cm Acrylic Wheel (White)
Spins very smoothly and is quiet, with only a soft whirring sound when spun fast.
The bearings and mechanism is sturdy, where you would not hear bumpy noises.
Perfect size for syrian hamsters, where they require a minimum of 27cm-27.5cm at least to run with a straight back with no spinal issues. (25cm is still too small for grown syrians, go for at least 27+cm.)
Not heavy at all for them to run on very, very smoothly. The full acrylic base is very sturdy and your wheel will not thud around.
