Yeah, other presenters make similar claims, which if it were true then they've got more money than sense and their house if full of stuff that they can't possible have time to use.
I think the wording may be important, i didn't see the bit but if they say they use everything, implying they've bought it and use it regularly, then clearly they are bullshitting as they can't possibly afford all of the stuff nor have time to use all this stuff. On the other hand, if they say they've tried the stuff they sell, then that could be possible, ie if they were given samples to try the product but they don't actually buy or use every item from that point onwards. hope that makes sense.
