I hope not!
Authenticate4U is based in the UK and has multiple brand specialists. They are reputable, IMO.
***************** is US based, located in Indiana and has authenticators who seem to have multiples "areas of expertise," but they aren't expert, IMO.
Authenticate4U has posted on TPF (with one ID) to explain issues with their site, apologize for their previous inability to respond to requests, explain forged authenticity documents that used their name, and in all cases has acted professionally.
***************** has posted on TPF (with at least 5 IDs to promote her site and has been banned on at least 5 different IDs.
Notice that ***************** hasn't come to this thread to apologize for the inaccurate authentication, and although the seller's listing was removed, I bet the seller who paid for the "professional" opinion hasn't received a refund.
Another thing ***************** does is offer a service where buyers pay $9 (on ebay and bonz) for a pre-purchase authenticity opinion. This is the same thing we can get here on TPF or the ebay boards for FREE!
She can't, because she's been banned and no longer allowed to post here. But she has a few longtime posters that are her "clients" that I'm sure will jump in when/if they get wind of this thread.
