well...besides Phil *ahem*. I'm curious how they stack up. I can't seem to get my windows clean and it's pissing me off. I need a good towel solution. Uber Hi Tech Glass MF
I haven't used the hitech ones but I have the regular uber glass towels, and have been using them for a couple of years now. I always follow up with a dry MF towel afterwards though, to remove any streaks and excess glass cleaner.
