Hitachi is a well known company for the large production of electronics appliances. I brought a Hitachi 1.5 ton split ac in 2 year before and I found some anomalies in this product. Though these have a large number of features but it requires frequent maintenance. The battery consumption of the remote is very high so you have to change the battery very regularly.
Also I have had to impart regular cleaning of the mesh to ensure efficient and fast cooling ability of the ac. So within a few days after cleaning, time it takes to reach the desired temperature quite high. The compressor is very noisy and create difficulties at the sleeping time.
