1.) This disposable pen actually works. From the second I opened the packages, I have had zero problems with the operation of the pen.
2.) It is smooth until it gets close to empty and then it scorches my throat. Could very well be a me problem and not an issue with the pen itself. I do feel as if I am leaving a more than acceptable amount in the tank because of the burning.
3.) I would love it if the battery operated a little longer, but I am a heavy user so I can’t really complain too much.
I was a fan of the AstroStiks when they worked, but this has been a wonderful and top notch replacement thus far.
