As far as I know, they only recently came to the forum and most of the forum users heard about them for the first time then. It is certainly still new to Bitcointalkers.
They paid 100 users to use and review their service. Did not a single one of these users continue to use the service afterwards? That's a pretty big red flag.
Aside from pricing which i find rather high (especially because i live on developing country), i got stuck few times (either due to bug or mistake on their guide) when i attempt to move my Bitcoin through few means. So i wouldn't be surprised if nobody continue to use the service.

Even though those 100 users who review their service did not continue to use it afterwards but everyone of them (expect a few) review their service top notch and excellent

While many review has positive sentiment, i recall only few say Mixin Safe is excellent (or other similar word). Fair amount of people complaint about phone number requirement.
