Summary: Personal Experience Overall quality is good. Usually like to keep a few of these in my inventory. These seem to be a unit that businesses like to rent frequently. This is surprising to me, because the Powerlite 78 is one of the lower end Epson models. At 2200 Lumens, it's a very good picture quality for a economy line projector. Over all not a bad projector for the price. Not really what I'd call business class, but it does get the job done.
Summary: I ordered this because of price and good online reviews. I also was cautious to order the "Apple Compatible" version so I can use it with my new MacBook Pro 13". Well, apparently, I don't have the video connections on my apple 13" and USB will not work. Maybe if I got the 15"...Oh well. The product is very easy and very good quality. It's just I'm a little irritated that it didn't tell me (or I didn't see) that USB will not work with Apple.
Pros: Great picture quality, Reliable Performance, Small Footprint
Summary: Very nice projector, with plenty of lumens for well lit rooms. Cost was very acceptable. I picked this up for use on the road for my church and on mission trips. Time will tell how it stands up to being on the road, but so far, it has performed very well and seems very sturdy. Unit will connect to just about anything via both standard and SVGA connectors. For laptop or mini-pc's, it even connects via USB.
Summary: Purchased 5 for use in elementary classrooms. Easy install worked well with universal projector mounts. Replacement lamps are on the cheaper side which is a plus. Originally 3 Epson S5 projectors were purchased and installed, they lacked zoom adjustment on lens; making install more difficult. All in all great product for the price.
Summary: O projetor é muito fácil de operar e de ótima qualidade. No geral considero uma boa compra apesar da péssima experiência com a loja Carrefour.
Pros: O projetor é excelente, leve, bastante luminoso e tem ótima qualidade de imagem.
Cons: Aquece demais e o meu veio premiado com um Stuck Pixel. O Carrefour não tinha outro pra trocar e a Epson recomendou enviar para uma assistência técnica, o que ainda estou inseguro de fazer com o projetor novinho.
