This is one of the best air cooler for extreme hot places. it takes very low water consumption, takes very low electricity consumption, very low maintenance cost, and also service of symphony is very good.
If u fill complete water tank then no need to fill tank again whole night, it comes with special kind of khas so no need to change khas every year and also it comes with remote so need to come near cooler again and again for on and off. and cooler operating buttons are soft touch so no chance of damage.
Over all good cooler in that price. u can use all day and night because of very less electricity consumption. If u are planning to buy new cooler just Go for it.
