The projector is ideal for me because I can take it anywhere easily (camper, tent, in bed with projection under the covers, etc.) Good: HDMI, SD card and USB port - everything is instantly recognized. Sufficient brightness also in battery mode, which extends at least for 2 hours.. Projections on colored walls such. B. balcony walls etc.lassen adapt by a digital correction filter. The built-in speaker is very useful in mobile operation. Bad: (therefore point deduction): Loud fan operation, which is sometimes annoying.
Total Classroom part, we have already had a lot of fun with it!
