This is the Welch-***** set, not used but brand new, only charged the handle. It is a spare one since I had two.
There are others out there that work fine as well and are cheaper, but this is one of the best, I have some links to prices online so you can see I am giving a good deal.
It is actually the version with the Macroscopic Otoscope in the third link.
