4 KVA Double Booster

Amazing product. I'm wrtting this after 4 months of use. And I will say it is definately better than V gaurd's pricy stabellizers.

Nice product.Working good based on one week experience.

Stabilizer is excellent works perfectly. Having very lil noise while the AC is running and Sticker for wire has been wrongly mentioned so initially comproser didn't start, I need to un plug and replug the right wires and it got worked perfectly.. other than this I had no issue faced with the product.Stabilizer starts with 9 sec delay and voltage monitor in digital screen is good.

Very Bad product... within 15 day stabilizer failure...not working...For product warranty I call customer care...but no contact number working...How to contact them...?? This is big issue...And only South India has his office...north area no service centre...so don't buy north indian public...

Worth for the money paid. The digital display of voltage is good.
