Pros: LED lights do a good job of removing shadows. arm articulates easily, 10x mirror side REALLY shows those pores.Battery option makes it so you can mount it any where. Plug in option if you have electricity near by.
Cons: Batteries are a pain to get to when replacement time rolls around. No way to hard wire the unit (low voltage). 10x mirror side need you to be inches away to focus (think nose prints on the glass). 
Overall a good a good product with just a couple of minor problems.
