Optoma Pico Projector

+ LED's don't pull 200+ watts = energy efficient, it can be powered from a PC or Laptop USB/5volt transformer with high enough ampage.

- It gets quite worm, the transfomer it comes with didn't put out enough amps to power it, only to charge it's batterys.

+ Size - battery life

- Wont link to PC

+ Size and portability, good battery life, having 2 batteries supplied, image quality for price, build quality, general usefulness.

- No mains operation only battery, would benefit either a larger internal speaker or a headphone socket to enable easier use.

+ Reviewer left no comment

- Need a pitch black room, so this won't replace the office projector yet

+ Suspect my unit is faulty as there are few good points other than its miniscule size and weight.

- Focus too coarse, difficult nigh imposible to achieve an accurate focus.
Sound output terribly weak.

+ Light, very compact and portable.
Image is much brighter than people had suggested and can be used in a light room.

- Image is too coarse-grained for print fonts under 16pt to be readable.
Needs Composite to VGA connector/convertor that weighs as much as the device
Composite to VGA connector/convertor not supplied with device

+ Size, weight, brightness.

- Cannot connect to PC and cannot accommodate a media card, making it very limited in terms of content that can be shown, unless you have a Nokia phone or iPod (but then you still need to purchase the relevant cables separately).

+ Tiny but big picture

- Built in speaker is poor

+ Small size.

- Other than the small size, the product was really disappointing. I bought it for the purpose of presentations to small groups. It does not connect to the laptop from the USB, but rather through an AV link, which I can't get to work with my Sony Vaio, although I got two adaptors for this. For this product to really make any sense, it has to connect through the USB port and maybe also perhaps have a bluetooth option. I am actually extremely dissatisfied by the product and if I could return it I would (I don't have all the packaging in place because i thought it will work with the adaptors).
