TR950 is very good, and millions of sets have been sold all over the country.

The quality and stability are definitely fine. As for the signal strength, it is not the equipment that has the final say, but the coverage of the local mobile network.

This set of equipment is quite beautiful. The cost performance is also good.

It is also very convenient to use.

But ask the boss. I can't sell it to you second-hand. So the quality is hard to say. There are many refurbished devices circulating on the Internet.
