Been saying that for some time bieliever
A car produces 200 hp and weighs 3500 pounds.
The manufacture finds a way to trim 350 pounds. Same engine producing 200 hp, same body. but it is now faster and gets better gas milage.
I trimmed an ActiPatch, 12 cm antenna, down to 9 cm for use on my neck. It does a better job with pain relief and also lasts longer than the 12 cm ActiPatch.
IMO, this is why BIEL used the eye patch as their first FDA Clearance. A 12 cm antenna Actipatch is treating 110 square cm area while a 6 cm antenna ActiPatch for the eye treats a 30 square cm area.
