I bought this room heater in this winter @ 943 rupees.Its small in size & light weight.First 20 to 25 days it was working very good.Grade two in regulator was enough to heat my 10ft?12 ft room in 15 to 20 minutes.But after that its performance degrading day by day.Now I have to keep it beside me to keep myself warm, unable to make room warm.Another problem of this room heater is if you set the regulator at level three burnt plastic material like smell started coming within two to three minutes, so level three is useless.
I will suggest not to use this particular room heater.
