## Customer Reviews

### ⭐⭐⭐⭐⭐ works good but each channel is separate
*by A***K on January 21, 2024*

need to add a jumper wire if you want to have both channels controlled by 1 input, but they work well and a bargain for the price - terminals are hard if you don't know to place wire to one side as the screw is in the middle.

### ⭐⭐⭐⭐⭐ Low cost low voltage relay.
*by C***Y on February 14, 2022*

I installed two of these on my tractor for controlling a larger high current solenoid switch. I had to add a DC-Buck voltage regulator upstream of it, due to burning out the first one, since somewhat wild 12-14.5V was just too much for it (it worked fine for about a day, then died.) The second one has been performing flawlessly for a couple months now. 😀

### ⭐⭐⭐⭐ Simple, effective and they work!
*by O***B on September 9, 2019*

I used one of these to change the cooling fan speed in the control cabinet on a CNC rig.Basically a macro in Mach3 toggles a pin from low to high. This activates the relay that in turn switches the cabinet fans to high speed when the rig is running and back to low when finished.Yeah a fancier PWM temp control is another option but for the cost this with a down and dirty two-speed arrangement for cabinet ventilation. And I have three left over for several other controls to be added!
