I have had it for several years and it works properly, although the response when zapping is somewhat slow. Sometimes it loses the user's setting regarding the screen ratios, and it needs to be reset. I have had better ones...

It was preset in such a way that it wouldn't store channels in numbers 1-5. You have to disable a function in the menu to fix it, but the manual is ridiculous and doesn't say anything beyond channel tuning, so you have to figure it out on your own.
We haven't tried recording to a USB stick, for the basics it works so far.

On the positive side
Fast remote control
Easy tuning
Quick channel switching
PVR that recognizes high-capacity USB sticks

On the negative side
Quite often changes the channel numbering (if someone has set a specific numbering they want to see) and returns them to the original order of the first tuning
Although it supports firmware upgrade, there is still no improved version available on the manufacturer's website.

The sound when I turn it on is slow.... and the remote with the small buttons doesn't turn off the TV..... basically, it doesn't have such a function, so you have 2 remotes, a regular one and one for seniors....

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.
