Ive always done same as Bettr..I have never had any issues with my wiring coming loose..ever.I take a hammer smash the terminal then use a punch ,and punch three times.once on flat side,and one on reverse side on each of the joints,and I have always used Heat shrink rather than tape..works great and seals to form good too.Try pulling that apart???Id only buy that thing and mount it on a table if I were use it every hour..Useless to me.???Hammer-everyone has one at home (95%) Punch-3 to 6.00??And Shrink-6 to 8 pieces in pkg-Approx-3 to 6.00.?????? My opinion
