Very fast delivery, packaging very well thought out and very well protected all the parts. Everything was included no missing parts. The assembly was a good reference for assembling the unit, took less than half an hr assembling the unit. But that was an enjoyable project to assemble. The kit of parts is well thought out and made it easy to figure out how to assemble everything. Tested everything and all works as it should. Have been able to do some moderately precise engraving and cutting with the device. Very pleased with the capabilities of the machine and ease of use for what I originally intended to use it for.

This was my first time to try a laser engraver. The shipping was extremely fast. The instructions are not very detailed, you need to find a more detailed video. It only take me about 30 minutes to put them together(if you don't want do these complex job, you can buy a assembled one directly). Everything did go well after installation with the software. Really a nice little controller for GRBL. Plus the offline controller saved me a lot of trouble of leaving a computer hooked up to the engraver, I am happy with how this machine turned out and will be using it often.

Bien construite pour le prix très modique. A l'aise pour le bois tendre et le plexiglas, mais à la peine pour l'aluminium et le bois dur comme l'acacia ou le chêne. Fraisage alliages ferreux et cuivreux impossible.L'axe des X manque de rigidité lorsque le chariot est au milieu. La fixation de l'écrou du chariot des X est vraiment déficient. Ok après modification assez lourde consistant à :1 - Changement du moteur de broche.2 - Ajout de deux rails avec roulement linéaire sur l'axe X.3 - Ajout de 6 détecteur s fin de course, d'un arrêt d'urgence et d'un variateur de vitesse.
