They might be fine to use on cheap kit lenses, but, I would never let a single one touch my L-series glass. Why would I skimp out $12-$20 (the cost of a real Lenspen) on a cheap substitute, which may damage many thousands of dollars worth of precious glass? A microscratch is a scratch is a scratch. Whilst any optical defect may never show up in daytime terrestrial shallow depth-of-field imaging, when closing down aperture for low-light landscapes, the scratches may start showing through -- much like dust particles on the lens or on the sensor.
There is a warning on the Lenspen web site with regards to immitations.

Have you used or seen a so called imitation one?
I've used the so called imitation lens pens and they have all had the attributes of a good product. They have Microfibre brush and 2 sized Chamoise cleaning cups. Don't know what you're talking about.
There are warnings everywhere in regards to stuff. If you where to use an "authentic lenspen" incorrectly, you would also ruin quality optical glass.
so it's not the pen, it's how and when you apply it's function. Anyway, if you have not seen or used one I don't see the point.
