Are they do to much falsing when they are even brand new out of the box. If your a deep park hunter try to find the deep stuff and put to much side pressure on them the control board inside breaks without you ever knowing. They could even still look brand new on the outside. Bad thing is they still slightly work but not correctly. See it all the time in videos.
