O2Nails Smart Nail Printer vs ZIJINGM 3D Smart Nail Printer

Both machines print at 2400 dpi from a phone app, so image sharpness is close. The Smart Nail Printer is the better-documented, more polished device: owners rate it 4.9 out of 5 and praise the app, setup and build. The ZIJINGM is smaller and lighter and claims a 30-second print and 20-plus days of wear, but it has far less owner feedback to back that up. Buy the Smart Nail Printer for reliable everyday use; pick the ZIJINGM only if a compact, fast unit matters more than a proven track record.

• Choose the Smart Nail Printer if you want a proven, well-reviewed unit with a polished app and a ready-made FM10 cartridge.
• Choose the ZIJINGM if you want the smaller, lighter machine and its 30-second print time and 800-plus built-in designs appeal to you.
