Humphrey Visual Field HFA 740i with USB Drive

I have used this particular visual field for years. There is still plenty of life left in it. The unit was originally a floppy disk model but was later converted to USB before I had purchased it. There are flash drives included as well with the sale of this instrument. The only negative I would mention is that sometimes the fan gets a little loud at times. It has never overheated or had any unexpected troubles. Please contact me with any further questions regarding this equipment.
