Personal Projectors at Bett 2017

I was drawn to the Personal Projectors stand at the Bett show this year. There were some great mini projectors on display; some battery powered, wireless and with brighter image projection than the ones I saw a year ago.
I particularly liked the ultra portable projectors, ranging in price from £250 to £700, my favourite being the Pico Genie M550 Plus, Short Throw Wireless LED HD Projector (650 lumens with battery / mains), for £599.99. Details of this and all of their other offerings can be found at
