I have bought this product from a stationary store and I plugged it and switched on this to rescue from mosqitoes in home.I tried it for 4 days and there is no effect against mosquito.i can feel the smell only around the maxo machine and no more instant action felt as their statement.i spent my valuable 66 rupees for this and that became worthless now.i felt very bad of this product Maxo mosquito repellent.
