O2Nails Mobile Nail Printer M1 vs ZIJINGM 3D Smart Nail Printer

Both are compact WiFi nail printers that print designs onto nails and claim over 20 days of wear. The ZIJINGM is the stronger pick for most people: it lists a 2400 dpi resolution, a 30-second print time, 800+ built-in designs and Android/iOS app support, and it runs on a common 5V/2A supply. The O2Nails M1 is a simpler, larger-footprint unit with a 24V supply and an optional extra cartridge; it suits buyers who want a basic salon or home printer and don't need the higher resolution or built-in design library. Neither is a proven consumer brand, so treat both as entry-level machines and check cartridge availability before buying.

• Choose the O2Nails M1 if you want a straightforward WiFi nail printer for salon or home use and don't need a large built-in design library or high resolution.
• Choose the ZIJINGM if you want higher resolution, faster prints, 800+ built-in designs and phone app control.
