Review on 💡 Industrial Electrical Support Trigger with OPTO Isolation - HiLetgo Channel by Chris Bowden

I bought three of these control boards in total complexity 12 valves. Only 11 relay channels are functional, so one of the relay modules on one of the boards was not working. Not sure if the issue was quality control in production or damage during shipping, but the issue was right out of the box. They do their job but you get what you pay for so be prepared to get a spare or something.
