    Ordered an ARCO 55 for laser engraving. Have not used yet as I am awaiting a laser that I probably should have ordered from OpenBuilds but didn't. Shipment very quickly, very well packed, and extremely well organized into various build packets. Hardware was well marked and everything in the kit was present and accounted for. The OpenBuild assembly instructions on YouTube were excellent. GREAT JOB OpenBuild!
