Years of repeated finger‑prick testing left my fingertips thick with calluses, to the point where my sense of touch became dull. I also tried wearable arm sensor patches, yet the adhesive triggered severe itchy skin rashes. This device has been a total game‑changer. There are no pricking needles, no irritating sticky patches, and it fits easily inside my pocket.
