To get back on track
FlexUG4 is an awesome option, It will cover most HF possibilities, so if you were in the market for only one ACCESS implant, that would be my reccomemdation.
Now in typical DT Forum fashion, here comes the derail
If you want a business card sharing implant, that’s the FlexNT ( with a completely different antenna but the besterest performer in the small form factor flexes)
And your best security implant, Thats your ApexFlex / FlexSecure
Choo choo, this derail train is outta here
