Univerzální zesilovač signálu externí antény 3,5 mm Jack pro mobilní telefon

it is important that it arrived, it is quite late, the seller is not to blame, I sent everything in order, I haven't tried it yet, it can't work on the iphone, when the neighbor arrives we will try it on his samsung so let me know if the signal is amplified ..

Sembra che le fanno apposta a non servire a niente, se dicono che servono per antenne per potenziare la ricezione. Invece NO, non fanno niente, va via solo il volume, pessimo

Just got it in the mail today and mail was running late it fit my phone and hopefully it will help get some better signal for my phone thanks for it sellers and joom for it

Za tu cenu funguje dobře, počítejte s tím, že se rádiový signál bude trochu táhnout
