A major defect is unfortunately (was at least on my machine) that the projector only after 5-10 minutes the day before set sharpness reached, therefore the focus wheel align only when the projector reaches a certain operating temperature, yet I had the next day 5-10 minutes to wait until the picture without my help was sufficiently sharp, the problem I had not in the two previous models. A similar defect as I have read in the forum frequently during normal operation lose some devices the focus, which is probably due to the lens, the wording, or the housing which is easily deformed during operation (probably through heat development), so that the image sharpness must be regularly readjusted easily, the problem seems not everybody LG to be PB60G the case, appear to have been well made differently by the manufacturer.
As I read some of the forum and comments here seems the same problem probably also have some devices from LG and the LG PA70G HW300Y.
Can you leave again, readjust the manufacturer, you can probably make yourself easy, from what I do not recommend personally AWAY as the warranty is of course gone then when the device has been opened by hand!
The one with the different devices made you realize also that in some devices that despite the same image setting have a distinct reddish tinge and some other more bluish.
Here LG should improve the quality chin trolls times.
On the whole, I swear to the LED technology, although not yet as bright as conventional beamer but you have to make the lamp life no head, particularly suitable for those much more likely, in a darkened up completely dark room an LED projector is not the conventional beamer much after.
My 3 stars refer to it at least in my device sharpness after 5-10 minutes was satisfactory and the rather weak brightness gain for LG HS200G, otherwise I would have gladly given 4 stars, just because the projector is HD Ready 720p capable, the image in a darkened room is good, the body design is very appealing, so I would recommend it even to a limited extent.
