Although the colors can be a bit too vibrant, they can be tuned down in the settings to make them balanced. The projector is also bright, so you can use it in a family room for watching movies. Although the resolution is 720p not 1080p, the PH550 has overall a brighter and more detailed picture than most portable projectors.
Pro Works for presentations
The picture is detailed enough for data presentation. Also the overly vibrant colors are not an issue when presenting text slides.
Pro 3D support
There is no crosstalk (picture meant for one eye is seen by the other) in 3D mode, which is an issue for a lot of projectors. On the downside, there is just one 3D color preset and also a few motion artifacts can be seen. Besides that, the projector is bright and therefore works well with 3D content.
Pro Very few rainbows
DLP projectors often show flashes of red, green, and blue on bright objects in darker movie scenes. They are called rainbow artifacts. These artifacts are not a major issue for the PH550. They can appear every once in a while, but it's definitely nothing bothering.

Pro Rechargeable battery
The battery can last up to 2.5 hours, which is enough to watch one whole movie or give a lengthy presentation.

Cons
Con Text images are not good
Though pictures and videos are vibrant, text images suffer in quality with the laser focus of Celluon PicoPro.
Con Not suitable for very bright viewing environments
Celluon PicoPro's brightness of 32 lumens is ok for use for dark viewing environments. However, the image quality suffers a lot in very bright environments. Under moderate lighting, the user can limit projection size to 14-15 inches to attain clear images which makes Celluon PicoPro suitable mostly for one-on-one presentations.
Con Low resolution
The effective resolution is said to be nowhere near their claim. Instead of 1920x720, it is often stated to be even below 1280×720, closer to 640x360.
Con Crosstalk - mixed up colors
Basically, colors on one part of the image affect colors on another part of the image.
Con Lasers can be dangerous
It's not very well marketed by the company, but the 3R laser light can be dangerous for eyes. You might want to be careful when kids are around.
Con Flicker - headaches
A lot of people have complained about getting headaches or other issues from the scan process of this projector.
Con No android OS built in (not smart).
Con Grayish blacks
The contrast is a little low and makes the blacks seem rather gray. Though with the lights on, it doesn't matter, since any deep blacks would get washed out anyways.
Con Bulkier than most portable projectors
Compared to other projectors in its class, LG PH550 is at the upper end in terms of size and weight specifications.
Con No support for microSD
Amidst the wide connectivity range, LG PH550 does not support microSD.
