I have no idea which companies you are mentioning here,as there is only one,ARPwave LLC,whose official site is:
[URL=]www.arpwave.com
As Jamirok correctly stated above.
The ARP Technology is FDA approved and certified.
If you need FDA Status code and details I can forward those to you privately.
Let’s keep our focus on training here,though,as doubt “is a word describing only desire not to participate”.
