“Upgraded from XROS 3 Nano, as the form factor is perfect for me, unlike the regular tall "pen" that's typical for other XROS devices. I'm not big on mode adjusting, screens and 0,4 Ohm support, however getting another 3 Nano felt redundant. Turns out I was wrong on all counts, battery and puff trackers are amazing, as 3 left me hanging multiple times with no ability to charge. Liquids that I find too harsh or too sweet, I put on an 'ECO' mode and it's saved some bottles from being thrown away! For only 3 pounds more than I paid for Nano 3 back then, it's an amazing upgrade and I would definitely recommend.”
