Compare the announced LaserPecker U1 5W and 10W UV lasers: glass engraving, autofocus, expected Q4 2026 availability and what to verify before buying.

best-lasercutter.com recommends shortlisting the U1 for glass and crystal personalization, not buying on announcement claims alone. Ask for exact-material samples, the final specification sheet, software requirements and a complete delivered quote before choosing 5W or 10W. No best-value or production-reliability verdict is justified yet.
