Review on 💡 DIGITEN Solenoid Connect Normally Closed: Enhance Your Control System with Reliable Switching Capability by Andrew Walton

I have ordered 5 units for next day delivery for an airflow control project. The units are essentially what they are advertised to be. Apply 12 volts and liquids will flow. The power consumption is 400 milliamps, which is quite reasonable. Remove power and everything will stop flowing. However, here are a few things to note (of course your mileage may vary): * 2 out of 5 arrived the next day and 3 out of 5 arrived 4 days later. Kind of a shame when you're working on a project with a timed expectation of completion. * 2 out of 5 didn't work right away. One of them only required disassembly and reinstallation of the check valve. The other (and this is the unacceptable part) was clearly a used unit: * the cable lugs were badly frayed and bent to the side, indicating rough handling by the previous owner, and * the unit had a significant amount of liquid from previous owner usage leaks into disassembly, so based on my admittedly small selection of samples, here's what you can expect: On-time delivery: 40% Immediate success: 60% "Used" chance: 20%
