Costumers reviews:

I am so very satisfied with ALCON 458 Y.

I live in rural area, far away from civilization in the place where mobile phones don't have range and also classic Senao phones can't help me because there are a lot of mountains surrounding my house. So I decided to try ALCON 458 Y. This aperture with 2 x base and 2 x direct antennas works perfectly in this conditions. 85 km across the mountains was done without any problem and finally I can say that I have phone.

I would like to thank you and just go on with such a quality and full solution!
