I haven't used the Excel, but I have been using Hydroxycut due to the price. I have the Carb Enders, and I'm not sure about their effectiveness either, but I only bought them from the COD instead of a cheaper Walmart alternative because I had some $$$ stored up from losing during promotions. But I do think the carb enders help a bit.
I haven't purchased the supplements from Ebay, but I have ordered the Lites with no problems. The COD tries to scare you out of doing that because it takes $$$ away from them.
Bottom line is nobody knows if these supplements really work because they aren't regulated by the FDA. For some people they work, and some they don't. But they aren't required for the program. If you've gained .6, maybe look at your diary to see if you've taken any extra BLTs here and there (bites, licks and tastes). Or maybe TOM is due. If not, then you can go back to their supplements, or try a cheaper brand.
Hope this helps.
