My second one Maytech remote control now doesn’t work after 2 times ride in salt water. Display is blank, cannot charge. After that I sent the remote to Maytech for repair. After they received few days, I contact Eileen and she pitch me to paid $59 for exchange the upgraded second generate remote. Also, she said that they will carry out the inspection of my faulty remote after second generate remote has been released at the end of August. Btw, the remote is quite good if there is no leakage problem.
Do not have any interference between 2 transmitter.
Smooth signal “above” water.
