I am also using Techgear MB 902 and it is quite OK. I have used HDPro DMB, the outlook is OK and have LED display, but the user menu is too "Chinese style".
So far I have not found any BD ISO that BD-1 failed to play, including those downloaded from CHD or Silu and copied by myself from original Blu-ruy disc using AnyDVD. Portable mediaplayer with excellent display and HD-sound.
