Gyus my father gifted me this coller on my b’day . im fully satisfied with my gift given by my father. It has water level indicator which indicates that the water is full or empty. My coller looks black and white. The body of my coller is fully plasticied. The best part of this is that it works even on invertor. It throws air at 25 meters. It has 34 liters big water tank. The serive of usha collers is too good. This is my best b’day gift ever.
