Much better than I thought
This device replaced a mechanical relay on my 3d printer and is currently handling 12.5amps @24v barely warming up. Easy to setup and use and up to the job. Hold the large screw terminals when tightening as they are only soldered to the board.

Good printer much better than the cheaper, more consumer focused units. Fast.
