## What reviewers say

**Boox Note Air5 C** — Two whitelisted testers reviewed this exact model: TechRadar (lab-tested, benchmarked) and Digital Trends (hands-on, no measurements). Both praise the Pen 3 writing/note-taking experience and Android 15's open Play Store ecosystem, and rate it strong value against the pricier Kindle Scribe. TechRadar flags typing lag, heavy 440g weight, weak battery life, and muted colors; deep-lab outlets like RTINGS are absent. (2 sourced reviews.)

**Supernote Manta (A5 X2)** — Only one whitelisted outlet (Engadget) has hands-on time with the Supernote Manta A5 X2, and it appears inside a combined Supernote buying-guide entry (nominally the A6 X2 Nomad) rather than a dedicated Manta review. The take is qualitative with no measured benchmarks: the reviewer praises the larger 10.7-inch writing surface, the user-repairable build and the smoother FeelWrite 2 protector, while flagging the absent backlight and the pen sold separately. Dedicated Manta reviews came only from non-whitelisted outlets and were excluded. (1 sourced review.)
