First impression... very well made, with a reassuringly solid construction and weight.Arrives in a well padded/robust cardboard box, so hopefully will reach you in A1 condition. The finish is excellent, and after going all over it carefully, I can't see any marks or defects. Good to know it's not just a thrown-together tool... some extra care has been made in constructing this.It has the 180-degree front/rear swivel as shown in the listing, and you can lock it off in any position via the knob on the opposite side to the angle-indicator dial. It does take a bit of securing by hand, but once there it feels solid enough to prevent drooping while in operation.The support column just slides onto the track and is secured by a single knurled screw. After it's been used a few times, the bottom of the channel will inevitably show marks where its' been locked in place.I've uploaded a few pics just to show a bit more detail (including the motor and belt assembly). Hopefully they will give a bit more of a clue as to the overall quality of this rotary.You will have to do a bit of Google-research as to the suitability for using with your particular machine. I've already had a quick look, and while some have encountered a few niggles on some machines, most have been very happy with it.On an overall build-quality basis... 5-Stars.

Once set up correctly it will work with LightBurn, tested it on Acmer S1 PRO and Atomstack X20 and both allows me to engrave on water bottles.The jaws allow it to grab the bottle from the outer edge or with the included rods it can grab by expending on the inside edge. This makes this easy for both very large (tumbles) and very small round shapes (finger rings) etc
