De cateva zile a aparut pe alibaba clona DM800se, la preturi intre 196 si 204$, sau 245$ cu transportul inclus. Aveam in plan sa iau un dm800 pro, cu tuner M, dar parca imi face cu ochiul aceasta noua aparitie. Ceea ce ma retine, e faptul ca deja pe diferite forumuri straine multa lume se plange de probleme la acest receptor(nu functioneaza unul sau ambele cardreadere, probleme cu cccam, putine imagini pt acest receptor, s.a.).
Cineva spunea ca nu prea e recomandat sa cumperi, mai ales din primele loturi ale acestui produs, intr-un fel esti beta-tester pt chinezi, mai bine sa astepti sa se remedieze problemele semnalate de altii...
Ca idee, totusi, pe partea de tuner o diferenta intre tunerul M de pe dm800 pro si cel prezent pe dm800se , clona, evident se poate face? Care ar fi mai bun?
