Reliable, well built but not without its faults.
The original Photon printer has its faults but is reliable and well made. The later S version has some of the faults fixed but comes with terrible build quality, which is why I went for the earlier version.
The faults are a sloppy Z axis, which can be adjusted but with a fair bit of dismantling. Full instructions by Aycubic are available on Youtube, its not hard to do. The other main fault is that the light array is too centralised and does not print well in the last 10mm at each end of the build area. The light array can be replaced with the one from the Photon S which cures the problem, or just don't print at the extrreme ends of the area, like I do.
