im gonna have to disagree with you there. only because i was in this business regarding those things at one point. granted, when used properly, you should be fine, but statistically, not everyone uses them correctly. personally, i wouldnt risk anything of that degree. better safe than sorry.
i do know many people who have used them for a long time and have been fine and have nothing but good things to say, but ive also heard plenty of really awful horror stories. if it works for you, great, but for me, i think ill pass. thats just me though.
