You have to remember that BIEL is a VERY small company. They have 12 full time employees ! Could they have been more aggressive in marketing the knee and heel products ? Absolutely, but that's just my opinion they have limited personal and resources so it's easy for me to second guess. They have to prioritize given they are such a small company. I think they chose to focus on obtaining additional FDA clearances to give their small company additional value for an eventual buy out. JMO $BIEL$$$
