ML750ST , I,ve run this nearly none stop since I got it over a year ago being disabled it helps me to see better and being able to take it with me helps, done lots hours with the xbox on this none stop for more the 48 hours at a time and its handled everything. light nd small what more could you want also my rooms arnt that big so the short fall on it helps a lot.
What a bright idea for road warriors.
James D. Feldman, CSP, Chicago, IL, September 2016.Aangeschaft bij Stampede
As a professional speaker I needed a small but powerful projector to put in my MacGiver carry on bag. This packs a lot of technology in a small footprint. It blows away anything else on the market. I am know as The Bright Idea Guy™ and this projector is one of the brightest ideas I have seen in a long time.
For anyone that presents to anyone about anything that uses slides, videos, movies, or other 'projectionable' materials this is a projector you have to consider if you are a road warrior.
super portable y liviano
Adriana Zangarini, Miami, May 2016.Aangeschaft bij B&H
Excelente video beam, super portable y liviano. Tenia el 750 y decidí cambiarlo al 750ST para poderlo proyectar mas cerca de la pared. Se los recomiendo sobre todo a los que tienen que estar moviéndose constantemente.
My review
Edison Pham, Toronto, April 2016.Aangeschaft bij AVS Unlimited
Bought ML750ST for my company and its a huge upgrade from the travel projectors we used to carry. Its so small, compact and most importantly - very light.

Its everything we needed in a portable projector.
Amazing for the size
Joe Russ, USA, March 2016.Aangeschaft bij
This is a brilliant projector for the road warrior. It's small, but very bright for the size and able to create a fairly large image in small spaces.

The color is much improved over the 500 lumens model and feels natural in all modes except the brightest.

The built in media player and file access features are awesome and allow you to share videos or photos without even needing a tablet, phone, or laptop.

My one downside is that at 700 lumens the project is not bright enough to view in ambient daylight conditions. But works awesome in any darker environment.

A very special purchase

I have used Optima projectors in the past and got an unmissable offer for this one. I cannot believe how small it is, how easy to use, and what a clear picture it gives. I hope to use this on many happy occasions in then future. It is so easy to set up and use. Thanks for this.
