U can trust microtek brand itself . I m using it from 7 years and I have not a single issue . It is totaly great . 10 to 12 hours of backup on normal uses .
There is no or very low mantinence . It comes with great solid body and its design is also quite good. With its ups function there no interupstion or any kind of fluctuations. If u want to buy u can blindy trust this.
