I usually say that Monster-brand products are overpriced, overhyped crap that no one should ever buy. That's because... Monster-brand products are overpriced, overhyped crap that no one should ever buy. But the one exception I have to make is their screen cleaning kit. It comes with a gigantic super-soft cloth and a solution (some sort of distilled water/polymer mix) that gets out most any smudge, yet is gentle on screens. I've used it on every bit of electronics I have. I love the stuff. It's $20, which seems pretty steep for a cloth and a bottle of goo, but it does the job and seems to last forever.
Odd that the one product Monster makes that I can pimp with a clear conscience is the one product they never advertise on their own.
@MacMontana: Point taken, but I'll vouch for this one. 🙂
