Have Nikon (now the new generation thanks to free exchange via Nikon), Wasabi and Strobe Pro (Canadian Godox rebranding).
The Wasabi has worked well for me in the D610, D7100 but will not work in the D500
The Strobe Pro works well in all three cameras.
Years ago I did get burned with a nikon-knock-0ff bought on eBay. If the price looks too good to be true - it probably isn't a true Nikon. That one was for my D5100 and while it works, I don't use it because I don't trust it and have three real Nikon batteries for that camera which is more than enough.
Seems with third party batteries and the D500 it is real hit and miss - best to try before you buy, or buy one that someone else has found to work in the D500. Still no guarantee
