20 cm wheel is only okay for dwarf hamsters or mice but definitely not for rats or even syrian hamsters! It will lead to problems with their spines.
The wheel itself might be okay (I don't have it, so can't comment on quality) but only for the smallest of rodents.
I wish manufacturers stopped taking deceptive images... *sigh* And owners educated themselves better before purchasing supplies.

An ideal running wheel for a large hamster like a Syrian hamster is usually at least 28-30cm in diameter or larger. This helps ensure the hamster runs naturally and comfortably, without being forced to arch its back excessively. https://slitheriogame.io
That's a really important point about the wheel size! I totally agree – like needing the right size sled when playing Snow Rider 3D! Good looking out for the little critters. https://snowrider3dfree.com
