Hi
Iv just had a look around and eBay seems to be the best place to get parts for this mouse
Overall there aren’t many parts (just replacement feet and things like that)but there is a few faulty ones that you could use as a donor to fix what’s wrong with your one and their not to expense ether
If you let me know the exact part your needing I can find it or find a donor mouse for you but it’s entirely up to you
Hopefully this helps
Any questions please ask
Thanks:-)
