Piece of Junk
The media could not be loaded. Please dont buy this product. Have faced multiple defects since delivery. Their customer care is practically non existent. When you call them they will put you on hold for 10 minutes. They will approach you on whatsapp & tell you to get it repaired from local electrical shop & that they will pay for it but they wont. Ive already spent 5k to get this piece of junk repaired. Better to sepend some more & go for reputed brands

Excellent Stabilizer. But...
The media could not be loaded. UPDATE 27 AUGUST 2024 :Stabilizer is working well still after 4 years. No issues whatsoever. Just adding one point if you are shifting to new location or buying lots of big electrical and electronics products at once instead of buying separate stabilizers for each of the item like Refrigerator, TV, Washing Machine etc., you can just buy this one for half the price and it's going to work like a charm.ORIGINAL REVIEW JULY, 2021:Overview, Warranty and Order :I live in sub-urban area and with such location comes severe electrical problems. Not only power outage for hours but also bad voltage fluctuation problem. I have been researching for a good stabilizer for whole house and Choice was between V-Guard and Aulten. I picked Aulten looking at reviews and speaking to customer care twice before purchase especially on warranty as I am in South India and manufacturer/seller is in Delhi. Once convinced that warranty will be taken care which is full replacement with Aulten borne transportation costs within 1 year of purchase without hassles I placed the order.Installation :Aulten does not provide installation. We need to get it installed ourselves (electrician or self). Although I am a Software Engineer I like DIY at home. So after reading product details in Amazon and product page and with my existing Electrical and electronics hobby knowledge I went for installation myself but not without dry run using my Iron box which was absolutely no hassle. Once dry run with iron box was successful I just connect input wires from mains, output wires to home mains and most importantly Earthing and powered on and it was running smoothly.Usage :I have Luminous UPS 1100, 900VA, 756 watts model which is most common in India. I just needed to connect stabilizer during mains on condition as the power fluctuations are very bad and hover around 170-270 volts throughout the day. But my load is only light load on 6 Amp line. I realised after purchase maybe I could have gone for 3KVA model as customer care suggested or even 2KVA model but nonetheless even if in future I upgrade my UPS this is still good. So if you are looking for UPS upto 4000 Watts this is still good for you.But... Problem :As few reviewers have already mentioned buy this ONLY if you have severe voltage variations throughout the day. DO NOT BUY if for most of the day you have voltage between 210-240 volts. There is a real problem of unusual buck and boost voltages as other reviewers have mentioned especially Mr. Devi's review. I have observed exact same voltage output problems when voltage is between 210-240 volts. For this I suggest company to upgrade circuit logic and add automatic bypass. This is extremely important so that when mains voltage is between 210-240 the stabilizer will just bypass. V-Guard stabilizer has this feature but it has other problems which is why I didn't buy that. But in case your voltage is outside of 210-240 most of the time then this is excellent choice.Conclusion :Excellent purchase overall despite few problems as mentioned above. I can recommend.

Horrible Customer service and zero support.
The product I received was defective. However the main issue is customer service. To start with, the company was supposed to provide installation support, but they called up and said that they cannot provide support in my area. Most probably they have good support only in and around Delhi. They asked me to find a local electrician to do the installation. As soon as we installed the product and switched it on the Mains tripped. That's when the nightmare starts. There whatsApp support assures you that "your call is important" and "an agent will be assigned shortly". On an average it takes them 4-5 hours to respond to a query. So you can only get 2 replies in one day if you are lucky. The first 2 days are spent on answering questions like "What's the input voltage in your area", "What's the thickness of wires you're using", "And what's the total load on the stabilizer".. When you try to reach out to phone support, you will typically be in the queue for 30 mins before the call drops... Just once I managed to talk to customer service when I chose the "Sales Enquiry" option instead of "Support". I managed to get an "engineer" to talk to me who asked me to post videos of the "issue". After that it was impossible to get hold of customer support the entire day. When I tried the "Sales" option, the call was picked up and immediately forwarded to the "support queue" (which, as we know, leads to a dead end).On whatsApp I mentioned to them that the stabilizer was "tripping the mains" on zero load - they actually asked me to install a 40A MCB , at HOME, which is very dangerous. I had no recourse but to return the item. Moreover, I th9ink, they did all this to make sure that it takes longer than the return policy period of 7 days - to ensure that I'm unable to return the item. I'm really glad I bought this from Amazon where the return went through without too many problems.
