Great as a flashlight.

My kids are using this toy mostly as a flashlight. At the beginning they projected a couple of drawings on the ceiling, then they wanted to project letters and after they have realized that the projection has a mirror effect that was that. As a flashlight, my kids use the toy often.

The drawing surface is a square piece of transparent plastic that is easy to clean with a wet wipe or just wash it with tap water, which is a way faster. The only downside that kids have already managed to lose it dozen of times, though the drawing surface sits snugly on the projector's top.
While writing the review I have realized that kids lost again the drawing surface, so I have tested the projector without it and the plastic top of the projector does the job perfectly fine.

I have tried the regular Crayola washable markers for drawing, but they have left a shadow of color on the drawing surface, so the Picture Projector wet erase markers that included in the set are the best solution. They wipe clean from the drawing surface but leaves color on the skin.

The "adjustable focus for clearer images and different sizes" function is not something to write home about. Doesn't make a big difference.

My personal dislike that the projector is not comfortable to hold - it's handgrip built in the way that it is painfully scratching my knuckles though my hands are relatively small, almost kids' size. Kids are fine, for their hands are smaller than mine.
