Review: Amazing cooler. Performs brilliantly as per cooler standards. - 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 desertcart 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.
