I have. THey both work well with shaved tinder. The blast match works very well. One handed operation etc. Better for one handed use than a Spark-lite in conditions where you have to use gloves. Only real issue with it is the tendency of the sparker to drop out. Glue it in place upon purchase. Striker Force is good as well. Very robust. I have replaced the WetFire tinder in the handle with Tinder-Quick. It's too heavy and bulky for on body carry. Has a place in a backpack or vehicle kit. Need's two hands to operate.

So far as I am able to tell (and I own ferro rod's from all of them) there is no differance between MagFire, LightMyFire, Firesteel & WebTex. They appear to be identical in all respects. They look to me as if they are all manufactured by the same company(s) and branded/packaged as required.
