Query: Good controller but,

This is great controller and mine was great it didn't have any probloms and its been 3 months. The only thing is, it uses 4 AAA batteries and I bet you the light uses more juice then connecting to the reciever. I had to change the batteries after 3 weeks. The only time the light turns off is when the battery is low.
