Summary: Nice bright picture for an LED projector (and this is my second LED projector, I am using an LG HW350T in parallel). I am mostly using it for watching sports or some videos now and than. It has a good enough color accuracy for these purposes. Due to the unusual shape of the color dots, sharpness does not stick out and when watching photos it looks slightly more blurred than the pictures really are. So in summary, it is bright, color is OK, sharpness could be better.
Pros: Great display, great form factor. Solid build quality, and great image quality at various ranges. And really nice and quiet!
Cons: Wifi does not work. You can't even enter the setup screens. Contacted ACER support 3x, even worked with Level 2. After purchasing the optional USB WiFi dongle, it still did not want to enable the WiFi setup. DO NOT buy this unit if you WANT WiFI.
It's very portable and as bright as traditional non-LED projectors ...

Summary: It's very portable and as bright as traditional non-LED projectors that have twice the lumens. However, it doesn't have an optical zoom to make the picture larger or smaller, so to adjust the screen size you have to physically move the projector forward or back. Keep this in mind if you're buying the projector to mount it. It also lacks a freeze picture function. You can blank (no-show) the screen, but if you want to freeze it you should look elsewhere.
Summary: Its Ad said this projector would support wifi video connection, even support four devices in real time. But it require a USB wifi adapter which is sell separately. The worse is the working adapter is only produced by ACER, which model is UWA2, which is not sell in the U.S. area. Yes! IT IS TRUE! The only way is buy abroad, which would be 100+ bucks. By the way, on this total price I could buy other projectors having build in wifi. So I buy a Google chromecast to instead.
Summary: I use it in my room with a projection size of 100'' to watch movies on a brown wall and the quality is very good. A bit noisy. One issue was that with the Black colour enhancer setting enabled, the projector did suffer from the issue of periodic signal dropouts, irrespective of the source. I hope a firmware update will fix the problem. I submitted the problem to Acer.
Pros: Easy to setup., Picture and movie quality., Usable with a USB flash drive.
Summary: We've got some pretty specific needs for our projectors - which we use for work. They need to be light, bright and easy to use. We've been looking for some time to replace our old Sharp Projectors and have been considering LED units as replacements. The brightness of which - has been steadily progressing to a point where we think - they'll be good enough. Recently we took the plunge and bought this Acer K335. But not without trying the Optoma ML750 first.
Summary: Habe heute den K335 erhalten, und leider ist er nicht zu gebrauchen!!! Der Beamer startet alle 2-3 Minuten neu (Reset)! getestet mit FireTV und Receiver. Wie kommt das Gerät so durch die Qualitätskontrolle? Wie kann man so etwas unausgereiftes verkaufen.... Kann es leider nicht weiter empfehlen!
Summary: Technisch gesehen hat der Projektor meine Erwartungen voll erfüllt. Selbst bei nicht komplett abgedunkeltem Raum erhält man ein wirklich gutes Bild. Als nachteilig werte ich allerdings, dass der Projektor wohl bereits gebraucht gewesen ist, da weder ein Handbuch noch eine der angegebenen CDs oder ein VGA Kabel bzw Batterien für die Fernbedienung beilag, obwohl dies in der Packliste angegeben war.
