The Hobbico Hot Shot are the best IMO.
I tried every brand with the meter on the end figuring it was nice to know if the plug was bad or not. I mean I purchased atleast 5 different brands, ALL of them fell apart, springs broke, clip broke, etc.
My buddies told me to get the Hot Shot and I have never looked back. LOL
I am sure others have had better luck than me, but I just like the Hot Shot
