Ok, so they were on sale for $5 and I bought one to replace my badmitton racket I hit Cicada killers with. Well I touched a fly in the house, kazamm, 2 AA batteries this thing works. Then a mosquito. I thought it was gimmick. My wife said I am glad you got a useful toy for fathers day.
Duct Tape, my return hose sprung a leak, so I duct taped it until I can get a replacement, only been in service 4 months. Will replace tomorrow and then plan out PVC.
