Yeah, they work pretty well, but the old Fireball gloves probably scared all of the people in the fire service off of any glove with rubber, and for good reason. A lot of guys got really badly burned with the rubber gloves. Thankfully, I came in after that era, but my dad and his truck crew on Detroit went with insulated leather gloves early on after a guy on the engine crew they responded with had his glove melted to his hand.
I switched to wearing Pro-Tech 8 Fusion gloves for work on the line. They're $60/pair, but I can very happily grab things I shouldn't and not get burned. They allow for a pretty good level of dexterity, which is about in line with a regular work glove-a pretty impressive feat for a fire glove. They are also really good for extrication if I don't have those with me.
