There's always mucho demand for reviews and comparisons between IPL and laser technologies and companies.
Ican't vouch myself for any of the info or reviews. Midwest sent me the link to his report so she's responsible for cudos or blame.
The link at the end points to a spam farm of text ad links which is somewhat unpromising but I'll leave that for you to judge. Certainly the report is well written and at 41 pages is much longer than the usual reviews.
I'd welcome comments on the report, or the voracity of the author if anyone knows.
