I bought this product 5 months ago and I was very excited about it but turned out that after giving cold air for 15 to 20 days then it just started giving only air as the pump started not working as it was under warannty I called the technician and he said due voltage the pump might not be working. I mean what is this voltas techician you are hiring also dont know about the problem though after few days when I again called they had sent another techinician who sorted it out and the cooler kept on giving some kinda problem so I was forced to sell this product at a low price in olx.in
