The Eleksmaker is one of the better Chinese kit style laser engravers on the market. The material is good quality and can be put together with relitive ease. They have built up a following and are repidly becoming a brand name - often imitated.
The lower three star rating is because they sent two idenitcal laser bracket plates instead of one bracket plate and one motor mount plate. Fortualtly I had the equipment nessasary to cut a suitably large hole in the acrilic as well as the four screw holes. A case of bad packing - which means someone else has the other duplicates.
Unfortuantly it didn't end there. The laser mounting bracket itself is very slightly skew. This can be countered by adjusting the four thumbscrews.
Having said all this I would still recommend EleksMaker Laser engravers over the cheaper options.
