Has anyone used the DNA Appliance and gotten results ?

Has anyone here used the Vivos DNA appliance or mRNA appliance and gotten desired results or has it made things worse ?

I had four molars extracted for braces when i was around 15-16 years old. Now, my smile feels narrow. My jaw hurts and i suspect i may have OSA (sleep apnea) so considering the DNA Appliance. i also have a mild overbite which i think affects my speech as well so I am hoping the mRNA appliance will help reposition lower jaw. Grateful if anyone can provide genuine reviews and experiences.

I am based out of india and Dr. PV Girish (The Right Bite Clinic - https://www.tmjindia.com/vivos-dna-mrna-alf-appliances) is one of the 2-3 providers of this device here. Has anyone availed MSE or DNA appliance specifically from this clinic and do you have any reviews about their treatment ?
