An Uplula reloader weighs about 2 ounces and is less than 3 inches tall. Fits in the palm of your hand. Won't take up much space. In fact, it takes up less space than, say, a roll of hockey tape...Maybe we're talking about different reloaders?
As a CCW instructor, every student that has borrowed my Uplula (strange name, I agree) has asked where to get them and how much.

I've never seen guys on the gun range with hockey tape on the fingers. That's just weird.
