initially I very excite by this product because I view it as a portable way to project larger version of myself to other . in particular , I be interested in appear 7 + foot tall to other in a business context . unfortunately , this do not work out as well as I have anticipate . quite possibly due to the fact the Optoma pk301 be only capable of create a two-dimensional image . on the upside , the pk301 occasionally send I through time in a uncontrolled manner . I also see from other review that this be not a uncommon occurrence for Optoma projector . I think the `` net net '' here be that it be a mediocre business tool but a effective , though unpredictable , time machine . I be actually in the process of now try to contact past-me by travel through to time to warn myself from purchase the Optoma pk301 in the first place . I think that pretty much say it all .
