It works very accurately and efficiently with the input voltage and output voltage. Decent look with intelligent voltage control. It has copper windings which is great.

Thus, opted for this stabilizer for the safety of my ac. It is a valid product from them and i am happy with the purchase.

Installation is very easy. They provide a pair of long screws and guide on paper for drilling space in wall. The product comes with screws and plastic bits so all you would need is a drill machine if you want to do it yourself.

When the input voltage is 230 volts the output is 198 volts. Keep on tripping at 190 volt and below not able to useac during complete day. Whenever there is electricity fluctuations it makes a lot of noise.

I recommend not to purchase this product as the product is not matured enough. Many pieces have manufacturing defects as seen from other reviews here. Highly non recommendable. A shame on v-guard for this product.

Some defective items fail within their warranty period. They claim onsite warranty but you have to take it service center all by yourself.
