This is a very important product especially for those in research and development. Given it's specialty nature, I am hoping it stays kept in stock. I think this will take off one day, even if not as soon as we may hope for. Already a fantastic item for it's intended use too, but I see even more potential with this as is. No need to change anything. This is uniquely perfect.
