This cooler costed me 18000 and it has been the my worst experience with coolers ever!! The problem started in the guarantee period and is continuing till date. First the fan system got burned, then other issues came erupting every now and then. Till date, I have spent over 10000 in getting it repaired, and I am talking about a single cooler. Mind you, I purchased two together! Both have wrecked havoc in my life! I repent buying an AC instead of this useless cooler!
