Review on Schrader 20250 Core Removal Tool by Kevin Singleton

Although the tool looks like it could easily remove some Schrader valves, I don't understand the odd design - I assume it would be for bike tires or something else where the valve doesn't is planted deep Also, apparently I didn't know that there are 2 different sized schrader valves and this is a tool with a smaller diameter valve. I think since the seller is the valve manufacturer he should know that there are 2 sizes and advertise that these are closed port valves rather than assuming the online buyer knows about it. but it's mostly my fault that I'm trying to learn as I go. It would be nice if they mentioned it somewhere for those of us who aren't mechanics. All in all a decent tool but a bit pricey for what it is in my opinion.
