Difference between Emerald S6c & Signia Pure 3 Primax

I’m having trouble figuring out the Difference between Emerald S6c & Signia Pure 3 Primax

Are they comparable? Thanks

Emerald 6C is Rexton’s version of Signia Pure Primax. The Primax 3 is their entry level aid. You don’t state the level of the Emerald’s. There’s a 40, 60 and 80, with 80 being the highest and the 40 being closer to the 40. They are not identical. Signia’s software has more adjustment’s available than Rexton’s, although they both use Connexx 8. Costco’s Kirkland KS7 is similar to the Rexton Emerald S 80.

I appreciate your reply. It seems like for $200 more the Costco Forte is the better value. Better technology for background noise, 180 day return etc etc Thanks

Better technology for background noise
