Bought this as replacement remote for my Wanbo T2 Ultra.
Old original remote (left one in the pictures): slow response, buttons no longer responsive, remote dies after 10 mins of usage, unusable bluetooth remote.
New remote (right one in the pictures): responsive buttons, responsive bluetooth and microphones, still working after prolonged usage.
Differences of old and new:
Color: Same black color
Shape: Old remote has a round shape in both front and back while new remote has round shape in back and flat in front
Aesthetic: Both remotes have crisp button prints. Buttons in new remote feels smoother when compared to old remote. Old remote features green PCB while new remote features black PCB. New remote shows signs of better PCB aesthetic and have a serial number.
UI: Both remotes have same functions with the buttons. Mic also works with both remote. New remote features two LED indicators - red LED is infrared signal for projector functions (focus, keystone, etc.) and green LED is bluetooth signal for Android TV controls.
Perfect replacement remote!
