This company is not serious at all. I do not recommend it. The trip was unsafe with a driver going too fast. People were sitting on the floor as there was not enough seats available. The bus was also full of packages and we spend two hours driving in Mandalay to pick up people and packages before going to Bagan. I won't risk my life again with this unprofessional company.
It would really help A LOT if you put on your website a map with the location of the bus station in Mandalay. The taxi driver himself was not sure where to leave us. Also, it would be very helpful if there were some signs in Latin alphabet at the station (Mandalay-Bagan, or the schedule), to be sure you are in the right place (everything is in Burmese and almost nobody speaks English...). Other than that, the trip was just fine.
