Creality CV-Laser Module 1.6W compatible with Ender 3/S1/S1Pro/CV 01 Pro

> Comes in a tight Card-Board Box Creality Branded and with hard-foam sections housing the module and accompanying items.> The Laser Module is small, with adequate cooling means provided (2 fans).> The Power is just adequate for etching on soft materials (wood, paper, felt, leather etc.)> There is no Focusing knob, which should have been present, so You'll need to manually adjust the height.> Enough profiles are provided to test run before You start on actual projects - Kudos to the seller> Works with PWM controls only, Best result at 2.2Khz, 92% duty cycleWhat You get:1) over 7-8 profiles to engrave, including wood, Cardboard, felt, laminates and so on.2) Laser Protective Glasses pair (material is acrylic, Green colored); It works!3) 3-Wire flat cable with P-03P female connectors on both ends4) CV-Laser Module - This is without Focusing Knob, so the Laser Protecting cover will almost rub against the profile at times or look like so...5) A M2 wrench, few screws6) 1 fixing plate, and the other guide plate is with the Protecting Cover7) The User ManualVerdict:Don't buy if You're planning to metal engrave or cut-art on wood, 1.6W Optical power isn't enough.Buy if You're beginning and want to spend time learning, since this won't hurt Your pockets.The product has very limited application/utilization primarily restricted by the Power output.I'll return since it couldn't match the fixture requirements on my desktop setup.
