Bests & Worsts Reviews from Amazon

I was surprised by the quality of the unit. It is very close to a professional model. Handy for a spare unit at the clinic or use by a nursing or medical student. The price is unbelievably economical. There are extra features like available magnification, two spare bulbs and an added eye chart. This purchase is hands down one of my best investments so far. I'm very pleased with the company's attention to quality control and their 100% guarantee.
