In 2015 and half of 2016 TRXC major focus was on Surgibot. When Surgibot did not get FDA approval in April 2016 they turned their focus to Alf-X now called Senhance. They have come a long way in a relatively short period of time! They decided the best way to market was to set up training sites and in doing so were able to get all of the human data that they needed to get FDA approval for Senhance. They are very wise/intelligent in their strategy! Please do some research people so that you know what you are talking about and investing in!
