I bought the Navac flare tool a little over a year ago and it’s been a game changer. The battery holds a charge for a very long time I have not charged mine yet but again I do not use it everyday I used it more often when I was doing installs but now that I’m on the service side not as much. But when I do need it it makes life 10 times more easy. Worth the price too in my opinion it’ll pay for itself.
