Amazon:

Buyers BEWARE, We have taken the Amazon link down as customers have alerted us to the fact that Amazon has co-mingled our inventory with that of counterfeit sellers.  They said it can take up to 5 days to separate the fakes from our stock. In addition we have finally received 2 orders "sold by Amazon and fulfilled by Amazon" expecting fakes as we have NEVER sold Amazon a single OPSol Mini-Clip. Both were surprisingly authentic but naturally so as they came from OPSol Mini-Clip's inventory sent to fulfill our orders. They had identifiers on them.

 

eBay has plenty of counterfeits but this seller is legit:
