Bought this product in 2017. In the last 2 years this product has robbed my mental peace. Got it replaced with a new stabiliser just after 2 months of purchase during the warranty period. Again after an year the stabiliser broke down and had to spend 1200 Rs. to get it repaired. In these two years not a single day has passed when my AC was working smoothly, thanx to the stabiliser. So after 2 years of mental trauma, today I have purchased a new stabiliser (V-guard VWR 400) to end my suffering. This company should be dragged to the court for harassing and cheating the customers. Further this is not an isolated case, since a lot of my friends and acquaintances are facing similar situations after purchasing this stabiliser. So it's my sincere request to all -- Plz plz avoid buying Whirlpool stabilisers for your ACs.
