The unit powers on perfectly and light is visible through all the various heads. It's a very nice solid unit.
Visibility through both heads is good, there are some minor specs visible through the ophthalmoscope head but nothing too major. The unit operates off of a rechargeable battery (included).
The handle doubles as a charger as well, so if you need to charge it, simply unscrew the handle and plug it in any standard outlet! Welch Allyn Charger/Handle - Part 71050. Welch Allyn Otoscope - Part 20000. Welch Allyn Ophthalmoscope - Part 11620.
