Had a little trouble programing it. It seems it received the signal from my other remote only if I placed the outside corner of the remote in front of it. It may just be my original remote makes it a little difficult. The remote itself fits nicely in the hand and it is easy to program once I figured out the above noted quirk. Would be happy to purchase again. Delivery time to NA was pretty fast considering the pandemic. Thanks.
Both English and Mandarin manual available. I mistaken it can learn the remote signal from the receiver. But after reading manual, I realised it is to copy the signal from a working remote controller.
