Product review (5 stars): Troubleshoot before purchasing
Purchased one and it works but still had the same problem with water overflowing.  So, I uninstalled it used a black marker to mark the current position of the water spring-tensioned screw look close you will see +/- and used a pair of needle nose pliers to decrease the water intake turning screw clockwise which could also decrease the ice size (but the ice tray will still hold the same amount if ice).  So, before you purchase a New one adjust the current one first.  My problem appears to be the water intake valve not planning on replacing as long as current condition makes ICE.
