I got two of these stabilizers along with my air conditioners(2 tons and 1 ton) for living and bedroom.
It has been 4 good years and both of them are doing their job well.
The stabilizer provides steady voltage outflow irrespective of normal fluctuations.
The stabilizer is fully automatic and does not require manual inputs at all.
The normal wait time after switching it on is around 20 seconds which is fine, usually I don't notice this time during regular power cuts.
The unit is nicely built and is very durable,
It comes with required fittings to mount on the wall near air conditioner.
I would strongly recommend V Guard stabilizer as it does it's job effectively, though initial investment is slightly high but it gives it back well on a long run.
