Yes they do work, we have been using 2 of the products so far...and have found the EXO does certainly give a body recharge. I made the mistake of taking one before bed one night and I couldnt get to sleep.
I now take them mid morning for a bit of get me through the day.
The FIT I am taking twice a day just prior to lunch and again prior to evening meal, and I can definately feel that it has the effect of reducing my hunger feeling.
I know of 2 other men personally that have been using the FIT and have lost kilos, by not feeling as hungry and therefore not "snacking"" in between meals.
The product range is growing too with now in Australia UMI with the Fucodian Ingrediant, which is based on brown kelp asian countries have been using for years.
