Review on Longang Digital Temperature Function Included by Stacey Littlejohn

I was happy to take this with me on trips. I tried this before leaving and it worked great. When I tried again on the way back, it wouldn't start. I even bought a new battery thinking it might be the faulty battery that came in the kit and still nothing. Tried again at home with another brand new battery. Nothing. I may have received a defective product who knows but it was very disappointing because returning it is more expensive than doing nothing.
