The media could not be loaded. Okay, having used a Crompton Greeve’s cooler for over 20 years, I knew I was gonna upgrade to Crompton cooler again. Visited Crompton website and zeroed in at the best product that they offer - Optimus 100 litre. And such large capacity cooler served my interests as well given I have a large living and dining room. I looked up for the cooler on Amazon and found sellers selling it at as low as ₹12000. However, none of them delivered the product at my address. And the one that could deliver the product, offered it at a sticker price of ₹15,990. I had no option but to buy from them. The good thing is that the seller delivered the product within 7 days given the seller and I are at the opposite corner of the country. Amazing courier service.Now the 100 litre capacity can last the entire day with low and medium fan speed. You won’t expect the cooler to chill the air like an air conditioner does. That’s not the purpose of air cooler. But add ice to the ice tray and it indeed chills the air fairly well. The noise level of fan is also well in control over many coolers out there. Again, don’t expect it to be as quite as air conditioner. It’s the reason why air conditioners are more than twice the cost of air cooler. The only minor gripe I have against the cooler is the noise of dripping water which, I guess, could be managed with better design.I have attached the video but it doesn’t give justice to how low the noise levels are. The fan noise is seriously low at low fan speed which is enough for my entire living and dining room. The noise of dripping water is a bit annoying.I have four star because of the sticker price and few imperfections. But I’d highly recommend this product for its reliability and build quality. Oh! And you’d love the auto-drain function which is so easy to use. It is a smart design. I wish the designers had applied such smart design to control the noise of dripping water as well.

I'm writing this review after 8 months of usage..Product is good..but customer service is worst to its peak..when we call customer care to raise a complaint on service center as the service of the service center for the product under warranty is not good, they will give back the number of the service center to call back.. That's how the service is..

Cooling 💯100 litre tank is more than sufficient. Easily cools a large area plus water lasts more than a day easily. Pump is strong and honeycombs are super quality which gives cool feeling even in the 48°C heat in my city. Never got such quick and good cooling from any coolers I've used so far.Air throw is good, covers large area of my room noise is least, which is very big plus point.Ease of use 💯Easy to clean, easy to drain than all previous coolers I've used. The "drain" nob and outlet provided at the back does it's job without having to open the cooler.The completely shutting off louvers help keep the cooler clean while not in use.Wheels are provided in the box.There're lot of options to fill water but the "inlet" given at back is best. Use pipe. Don't fill water from ice chamber.There're pump options given at back panel for summer or humidity. Keep on "high" during summer and "low" during rain/humidity. This option is very helpful.After sales💯Initially i faced some issues as i didn't properly understand some settings, so had to contact Crompton service. It was very easy to contact and they sent an expert within hours of calling and provided service free of charge. So very pleased with after sales service by Crompton.Overall best cooler I've purchased so far after trying both generic and reputed companies coolers.Very good cooling even in such extreme heat. Perfect for a small family. Least noisy, easy to clean and fill water. Highly recommended. Full Paisa Vasool!
