This is not directly related to this situation, but in general. I've been on numerous online forums since the late 90's from cars to ATV's to computers, etc. One thing I have learned and have actually been burned on in the past is basing purchases solely on reviews from online forums. Lots of these forums are owned by Kohlberg Kravis Roberts & Co. (who just bought out Internet Brands). They have strict policies regarding ANY negative reviews and/or comments about products sold and/or manufactured by any sponsors of their forums. On some of the forums anybody posting anything critical of any sponsors products will have their post physically removed. To this day, on the Corvette forum, there is one tuner who gives LOTS of $$$ to be a sponsor and he has blown up numerous Corvettes due to his bad tuning. You can't post about it on the Corvette Forum (CF) though, as it will be removed. See
-HERE- The result of this is filtered reviews. You only get to read about the positives and not negatives. This makes for researching products solely through online forums very hard, as you don't know who's a sponsor and who's not.
Anyway, when doing my research on the Kuuma I physically called and spoke to a handful of owners of the furnace. I found their reviews on Kuuma's site, used Google to find their phone number and gave them a call. Yeah, I pretty much stalked them....lol Everybody was very accommodating though and didn't mind me contacting them.
