I bought this **Kenstar Air Cooler CT 9924** from **Pai International(https://paiinternational.in/) showroom at Indiranagar, Bangalore** on 13th March 2011.
This cooler has never worked properly since the time I got it. It makes this loud noise like you’re running a diesel genset or an auto inside your room(Play the attached video) ->
To make matters worst Kenstar has a pathetic after sales service(which is outsourced to some generic "Customer Care" agency).
I had written a full review here - https://mouthshut.com/review/Kenstar-9924-mulnmqpnmn
But, looks like mouthshut has deleted it. Sorry about that.
Just as an update, Kenstar people replaced the faulty piece with a new one which worked better. But I didn’t use this cooler much(only for few days in peak Bangalore summer) to avoid spoiling it again after it was out of warranty.
Overall, it was a bad experience and since 2011, I haven’t bought any other Kenstar product.
