Optoma PK301 Pico Pocket Projector

Optoma PK301 Pico Pocket Projector
Optoma PK301 Pico Pocket Projector was a surprise when I received it. Package content was small, but I think a remote control should have been added with the product. 
Connectivity was easy, setting up was easy and the pictures were really vivid with nice contrast and colours. Surprised that such a small projector could do such wonderful job. I would give 4 star because of few glitches I think specially the adjustment ring for focussing - too small and quite difficult to do so. I have been using Optoma for last few days for about 3-4 hours without heating up, very minimal external sound but finds myself irritated when I have to do some adjustment. 
An accompanying remote would have been really good and should have been added with the product. 
iPhone/iPad/iPod connector were not able to ship in Australia unfortunately, and those could have been added with some extra charges. 
Focussing ring really needs to be better 
Overall, its a wonderful product, gives full 1080 resolution when connected via HDMI and connected to a power source very good resolution.
