The LG PH300 is a pocket class projector that offers a lot a features for a modest $449.99 MSRP. However, like most other pico and pocket projectors it has some significant limitations. In many ways this becomes a trade-off between size vs. performance. Larger projectors, especially lamp-based models, can produce a brighter image and offer much better built-in audio quality while the PH300 is far more portable and offers the capability for battery powered, cord-free operation that you won't find offered on those larger projectors. The LG Mini-Beam PH300 is being primarily marketed as a portable home entertainment projector, but easily doubles as a road warrior's super small and light projector suitable for making business presentations to very small groups.
