Query: sparks aren't as hot as you'd think

While kind of fun to play with (it does make a lot of sparks per strike). I found this to be a rather lame fire starter tool. While it says the sparks are several thousand degrees, I found it rather difficult (but possible) to light ideal materials like a piece of klenex and my gas stove top. Both took many tries.Lighting a plain piece of paper? I can't even scorch it. Good luck starting a fire with this thing out in the open with damp material.
