It loses channels randomly, one catches HD and one doesn't, if you go from channel 2 to 6 it's a black screen, you go back to 5 and then go to 6 it catches, it has a strange behavior, maybe I can fix it. It doesn't happen all the time but the problem is noticeable

In general, it is a good product. It changes channels quickly and does not freeze. There are two disadvantages in my opinion:
It does not display the program on all channels.
It does not have a setting to automatically turn off if it has not been used for a long time

Very good for its price. It is worth it for the elderly as it also has a remote control with large buttons. After a week of use, I have not noticed anything negative. The only thing I don't know if it exists or if I can't find it is how to put each channel I want on a specific number.

Very good and fast receiver response! User-friendly remote control with satisfactory range. Worth its money.

It has lost the channels-programs after a power outage, but not every time this happens. When I reprogram it, everything comes back.

Wonderful, small and discreet, it took less than two minutes to set up the channels and ready to go. Excellent picture and sound with HDMI cable.

Much better image quality than a crystal audio that it replaced and the second remote control is convenient. In the previous decoder, it was the first thing that broke. I haven't tried the USB input yet.

The channel switching is slow when using the numbers, while it is relatively fast when using the previous-next option. The program and information do not correspond to reality on most channels.
Given its cost and the two remote controls, I consider it perfect.
For movies via USB, it displays Chinese subtitles. The same subtitles in the same folder with the same name are okay but small in size.
I don't have an opinion on its "lifespan" as I have only owned it for two months (10/1/2023).
It is used with an HDMI connection.

Very good receiver. It's worth its money. Very good screen quality and the remote control is user-friendly. I recommend it!!

Amazing receiver, it has a remote control with large buttons. We got it for our grandma and she uses it easily and is very satisfied. It is unique, there is no equivalent in the market and it comes with a 3-year warranty from the dealership. I recommend it for purchase.
