The two products in the same category with the closest rating.
The OMTech K40+ 45W CO2 is rated 6.4/10 (Fair), not in our ranked top 5s. It is based on 37 Amazon reviews averaging 4.4/5 and the specifications stated in the listing.
Its exact listing states a CO2 source, 45 W as its lowest explicit laser wattage. These are seller claims, not our measurements: a wattage in the title often describes electrical input or a module rating rather than optical output.
Check on the exact listing and in the manual whether laser safety glasses for its wavelength, smoke extraction or a filter unit, a work support such as a honeycomb bed and the software are included. Never laser PVC, vinyl or unknown plastics, and never leave the machine running unattended. Our laser buying checklist lists the checks.
