Disadvantages:
-Low zoom (so you should keep in mind before buying canvas size and placement of the projector)
-ECO Mode in any operating be readjusted, also with regard to many other settings is the unit "forgetful"
-at the device itself is only the on / off button, all other buttons are available only on the remote control (with button cell battery: - /), which can however be operated on the projector sticking well in the bracket
since the disadvantages mentioned hardly play a role for me personally, there are 5/5 stars from me. represents for whom the low zoom no problem, the can be buying this product only recommended.
