Thanks for the reply ptluis. The return shipping will be expensive for me, I contacted the seller, he compensated me part of the funds. In the end it cost me $30, I can't be without the device now, it works somehow and well, it will suit my purposes. I wrote to Zeeweii, let's see what they answer.

I need to look for something compact with the same parameters, what do you recommend?
