Sukam is a good brand which is satisfy his customers very well but there are some problems in ups like some times it auto power cut the power or batteries of sukam is really good .backup of batteries is preety good. I used sukam from last 2 years its really good . Somethings are not not good but overall its good . If we compare than others so its better than some other brand . If I give him ranking than I choose 2nd position for sukam invetors. Afterall its thats why I used him from last two years . One more thing is its degin and looks is very good than others and its smart mode is too good .
