SpartinusWe test the adapter with Razer BlackWidow Ultimate 2016 and it works. So it is very likely the Tournament Edition will also works (we can't say for sure unless the exact same model is tested). There is no noticeable lag when using the USB interface with normal typing. However, none of us are gamers so we can't be sure the effect on gaming. With less than 30 dollar price and 100% money back guarantee, it is worth a try. Or perhaps we can loan you a unit and you report back how well it works? Contact support at handheldsci.com.
