How price order works

Lowest recorded store prices take priority over announced or launch prices, within the selected source market. Currencies use the dated EUR reference rates. Deposits and recurring charges are excluded from price order; missing prices stay last. Original price records remain visible.

The differences that matter

MIT supernumerary robotic fingers (2014)

Research on augmenting a human hand with two synchronised robotic fingers

Keep in mind 2014 research apparatus, not a currently available medical aid.

Dani Clode Third Thumb

Motor augmentation research

Keep in mind Research object, not a prescribed prosthesis or retail extra finger.

Battery claims use different conditions and are not a controlled benchmark. “Not verified” is an evidence gap, not a missing feature. Prices are dated regional snapshots. Deposits, bundles and historical launch prices are labelled. Brightness measurement methods and battery workloads vary by manufacturer.
