Awesome! It does its job very well and the setup was easy.
I used it by connecting it with a LAN cable to the provider's router to have internet in other areas of the house without losing speed with extenders

When it works, it's fine. It has plenty of connections both in AP mode and in Repeater mode, which is fixed upon restarting.

Despite being second-hand, they are excellent value for money. I used four of them as access points and one as a router on the same network.
Easy installation
Very stable
Good speed (you get what you pay for)

I am a student and I bought it for (wifi) so that I don't have to have my computer with an ethernet cable. So I found something cheap. It does its job decently. If you don't have high expectations, it's worth it.

Due to my job, this product is incredibly easy to use.. It is suitable for all purposes

It does not transmit the signal. It constantly shows "no internet access". I reconnect again and after a while the same thing happens. Waste of money

Only the ROYTER ZTE 108N is worth it with a range of 500 meters, with a slight setback in bad weather, everything else is not worth it unfortunately

I use it as an access point (I pulled a cable from the OTE router to the Tenda) for home use. It works perfectly, easy to install with a user-friendly menu, the signal range it emits is more than satisfactory, and the price is around 20€. Value for money!
It also has the capability for wireless repeater (without a cable), but due to distance (2 floors) and thick walls in between, I was losing 6-7 mb/s (my mobile phone couldn't even catch the signal from the OTE router in the spot where I tried it as a repeater).
Don't expect crazy capabilities for this price. It's simple and it works when you want to extend the signal, for example, to a nearby apartment.
