O2Nails Mobile Nail Printer M1 vs O2Nails X11 Nail Printer

Both are O2Nails WiFi printers that put designs on nails through a phone app, and both claim prints that last more than 20 days. The X11 is the stronger machine: aluminum-alloy body, 2400dpi resolution, about 1000 nails per cartridge and a 12-month hardware warranty. The M1 is the smaller, lighter plastic unit for casual home use; step up to the X11 if you print often or want a sturdier build.

• Choose the O2Nails M1 if you want a compact, lightweight printer for occasional DIY nail art at home and don't need high resolution or a long warranty.
• Choose the O2Nails X11 if you print regularly, care about sharper 2400dpi output and a metal body, or want a 12-month hardware warranty behind the machine.
