If you have read this review from the beginning then you know that I have mentioned a few times that I haven't exactly raved about picture quality when it comes to Pico projectors and the more specifically the Optoma PK301. Part of this inability to rave about it comes from the fact that I have seen so many great projectors that are designed for boardrooms and conference halls that are only a few hundred dollars more than the some of the Picos on the market. That being said, the Pico serves a purpose. It has a niche, but one has to know if the limited capabilities of the projector outweigh the convenient size and long life.
The Optoma produces a satisfactory image for the Pico category of projectors. Contrast is actually not bad at rated 2000:1. When actually viewing the projector I would have to say that the reality is far from the specified contrast ratio. One would not be satisfied if they were looking for a dedicated home theater projector for movies or gaming.
If you plan on just having a quick to setup, very tiny projector to convey an idea quickly to a small group in a dark room then having the Optoma PK301 would come in handy. It certainly would be a conversation starter based on its actual micro projector appearance.
