This is good and prompt stablizer. I have adopted this to my fride ane to samsung tv. if sudden voltage is dropped down it will alternate current and supply full normal current .
There are many products in market and they will give price low than this and they give warranty of one year but believe this v guard company gives 5years warranty and gives a full protection to our item or products. people who wants to get a real worth value for their money and good protection to their products from voltage problems should buy this .
