genreally satisfied with LCS products - one exception: LCS 'Better Bird Launcher' - electronics are a bit glitchy - doesn't always trigger, or functional distance from hand-held controller varies widely - frustrating when trying to precisely time a launch in a training session - talked to LCS' tech staff, who was unable to help - my solution: bought another after-market unit from a DIY guy - more reliable, but that too is a bit glitchy, so I use them both, positioned side by side - if one fails, the other usually works, though timing may be compromised, then when dog(s) standing steady go in and trigger w/hand-held when close enough or nudge retention bar with foot, thereby launching the stay behind bird - bit of a clumbsy work around - probably should try calling again to get the electronics replaced.
