Summary: Got hot during use. Sometimes cut off during use. Sometimes malfunctioned image projection during use. Was still good enough to have until it just quit working. Image quality and sharpness were surprisingly good. Shortly before return-period would have expired, it died and I returned it. Had trouble getting refunded. Hassle. If it didn't screw up, I'd recommend it highly. The customer support was as good as the product.
Summary: I bought this projector for business purposes after reading stellar reviews. While very portable, the quality is poor, and it is not very level. I would recommend looking elsewhere for a top quality projector, as this one is simply not worth the money.
Summary: Purchased one of these for use when travelling, primarily for sharing powerpoint and screens with small working groups. While the form factor is fantastic for stowing in your carry-on, the presentation capabilities leave a lot to be desired. Did not meet my needs and I have returned it (thanks Amazon for the great return policies). One problem that becomes immediately obvious on set up is that the provided cables are REALLY short.
Summary: The Optoma PK301 gets VERY hot. I just got it and I'm pretty sure it's gonna fry its insides pretty quick. I've tried to watch a movie through it's micro SD port but it's very choppy. As has been said, the sound is not worth having on. And it's not very bright either. For fun I played the same movie synced up on opposite sides of our room. One was playing on our TV and the other was projected on our wall with the Optoma. The Optoma didn't stand up to the TV at all.
Summary: I wanted to give this product a good review. I like the convenience and efficiency of a projector in such a small package. However, after only a few months of use, the HDMI mini-port on my projector ceased operating. I was initially impressed by the responsiveness of technical support. They sent me the necessary forms immediately so that I could send my unit in for repair. On Jan. 9, they told me it would take a few weeks to repair. After I called for an update on Jan.
Summary: The DMD processor chip will go bad after about 1 year of use. This has happened to everyone that I know who owns this projector. It is great until then, but be prepared to replace the unit every 1-2 years since there is no fix for this problem if it is not under warranty.
Summary: I ordered this to use as a projector thats easy to transport as I offer training classes/presentations which have me in different hotel conference rooms and other odd locations. The projector is small and compact but it is not nearly as bright as advertised, unless you have the lights off in the room it is hard to see.
Summary: I ordered this and promptly returned it after having it for only a couple of days. The light source is not bright enough. The room must be completely dark to be able to see it the projected image. Also, note the native resolution; 854 X 480 while the specs mention a maximum of 1280 X 800. This means that it will take a 1280X800 signal and down convert it to the lower resolution.
Summary: I'll start this review with a disclaimer. I'm a geek. This means I did a ton of research on the PK301 Pico Projector from Optoma before purchasing it through Amazon. In theory, it's a cool toy. However, some basic production faults sabotage any realistic use of this projector. I initially purchased it as a special effect for Halloween.
Summary: Bought this for a colleague in India who was going to buy some local tat for the same price. However, after following the instructions and fully charging the unit before first use, he was very disappointed that the battery only lasted about 15mins. The picture quality is fair but you need to have a dark room to get the best out of it, especially at bigger sizes.
