I think and hope that means you’ve decided not to go with them.
I’m glad, because I continued to do a bit of research after posting. Although I can’t prove outright they are scammers, there seem to be a number of very similarly-packaged products, with the same ingredients and claims made, but very slightly different names. I wouldn’t be surprised if these all traced back to the same company.
The common theme is that if you buy, you are subjected to a very, very hard sell to keep going and buy more. Some purchasers reported receiving e-mails and phone-calls several times a week, to enquire how they were getting on, and whilst the contact itself doesn’t seem to have been harassing or aggressive, the mere frequency of it was.
People who claimed the tablets weren’t working were told 101 reasons this might be, and encouraged to persevere and increase the dose, to the point someone was taking nine tablets a day - and obviously having to pay for that amount.
So it seems that if you complain they’re not working, you don’t get a no-quibble refund under the guarantee. Instead, you’re persuaded to double or treble the dose and carry on - thus pouring good money after bad.
When you eventually protest that enough’s enough, and you’re not giving any more chances to something that doesn’t work, you’re typically told that carrying on as long as you did (which you only did at their insistence, of course), meant you accepted the product, and couldn’t now demand a refund.
Review of a suspiciously similar product on Amazon.com (not .co.uk) also made the comment that about half the reviews were positive, and the other half negative - but the positive ones were NOT from Amazon verified purchasers. So it looks like the company has a network of people (or a few with a lot of aliases) paid to say good stuff about the product.
It’s really at the fringes of legality, because nobody claimed they didn’t get the goods, that they didn’t contain what was claimed (though I doubt many people have the resources for chemical analysis), or that the company was ever nasty or threatening. Instead, the company used a relentless charm offensive to persuade you never to stop, even if you weren’t satisfied the tablets were working. It’s harassment with kid gloves on.
Once you’ve bought, you’re never free of them.
