Two ways to fit a body
SQAI uses electrode pads that can be moved, worn with conductive base layers. VisionBody sews 24 dry electrodes into the suit and offers made-to-measure sizing. SQAI’s approach adapts to unusual body shapes. VisionBody’s is faster to put on.
Documentation
VisionBody’s clearance K222386 is public, with channels, frequency and pulse width. SQAI headlines an FDA clearance but gives no 510(k) number, and publishes no channel count or stimulation parameters.
Price and returns
SQAI costs $2,995 and charges a $450 restocking fee if you return it within the 30-day trial. VisionBody costs $1,890 with a 21-day return window. Neither has a subscription.
Verdict
Unless you specifically need movable pads, VisionBody offers more documented technology for about $1,100 less, and trying it costs you less if you change your mind.
