We have ordered this product over 60 times and counting!
We have used this item over 60 times in different clinics. Since first purchase, we have never found a need to replace them. The driver takes seconds to install, and the connection to our lab equipment has been seamless. The only concern is the Serial end only has Male connectors. Our adapter for lab equipment is also Male, so we have to work a little harder for cable management. From a functionality front, we wouldn't change a thing!
