Hello Welcome to the forum 
Yes there have been some tests around the poker table with various products. Here are some links so you can take a look.
This one has a post by a professional poker player and his experience with mones.
This one is from the ladies section but a good read.
I have a few poker related posts but they involve hot tubs and nakedness so I dont think they are what your looking for 
Hope this helps
Your GC will be in your email box in the next 48 hours
If you have any questions just ask
Have fun
