When you set it up the machine and the liquid bottle. It has to many hols from in to out. And its we had it for a long time. It was in our car for almost 1 year and in our left middile A/C vent. I has color it is only black. Its black is not dark its normal black. Still again the hols at the back I little more ugliness adds.
I feel there are too many hols the customers who buys this product ambi pur will cry because of the holes. Its not made of steel aluminium and glass its made of plastic. And ambi pur is not sleek .Overall this product is average.
