Anyone here using a Chinese fiber laser for actual production?

Been shopping around for a fiber laser for our small fab shop. Mainly cutting 1-4mm mild steel and stainless.

The price difference between Chinese brands (Raycus, Max, Bodor, etc.) and something like IPG or Trumpf is massive – like 1/3 the cost. Tempting, but also makes me nervous.

For those of you who actually run a Chinese laser in a production environment (not just a hobby garage), how's it been?
