Our editorial rating is an evidence index on a 0–10 scale. It is not a hands-on test and not an Amazon customer rating.
A commission is never an input to the rating. Read the full methodology.
The two products in the same category with the closest rating.
The LONGER Ray5 20W, 400 x 356 mm is rated 7.0/10 (Good), not in our ranked top 5s. It is based on 176 Amazon reviews averaging 4/5 and the specifications stated in the listing.
Its exact listing states 20 W as its lowest explicit laser wattage, a 400 × 356 mm work area. 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.
We link to the exact listing on Amazon, where the current price, stock and seller apply. The link is an affiliate link and has no effect on the rating.
No. This page is a listing-based comparison, not a hands-on test: we have not run or used the product. The information comes from the exact Amazon listing and its public review record.
