I bought a Boox Note Air5 C for university but found the colour e-ink technology deeply disappointing. I wanted a colour display for viewing diagrams etc but the resolution is so low it's pointless. The screen is so dark that it requires constant frontlighting, which drains the battery extremely fast (25% in 1 hour). It doesn't even last one day for me. Most absurdly, the magnetic case that comes with the device causes the stylus to malfunction - you have to remove the case to use the pen properly. (Watch the YouTube video called "BOOX Note Air 5C: The 5 Problems They WON'T Tell You About" for more about the issues.)WARNING ABOUT RETURNS: Returning this device (in original condition and with original packaging) would have cost me approximately 40% of the purchase price due to Boox's return policy (customer pays original delivery fees, receipt charges, and international return shipping costs). When I asked them to reconsider some of these charges, they refused any flexibility. (Compare this to Remarkable who offer 50-day returns with free return shipping...)In summary, don't buy this device unless you've thoroughly researched and considered its limitations and you're 100% sure it's the device you want.
