I agree with you the unit should work regardless of temp, Ph, wind speed or moon phase. If their tips don't work (likely) I would demand to speak to a Supervisor or anyone that has the authority to fix or replace the unit. Keep climbing the ladder and be such a PITA they would rather replace it than put up with your phone calls. It worked fine before and now it doesn't so something is wrong.

Do you still recommend the Poolbuster? I want to buy one.
