O general cooling is very good and quality which they use are very best.It cools down room very well and fast. We are using ogeneral ac from 5 years without any problem.I had tested this AC in summers and I must tell you, that 5 years old AC(at my friend home) was really effective and at night, when I even started feeling more cold, then I adjusted the temperature to some higher temperature and had a real peaceful night.Every corner of this product was properly manufactured and finishing quality is very high.
