Review on 🔧 Ultimate Precision: WayinTop Adjustable Voltage Controller for Optimal Control by Ryan Hampton

I seem to have had the same experience as other buyers here. One unit appeared to be completely broken (the LED did not light up when power was applied), the other appeared to be inoperable (powered on but did not work), and one worked as advertised. i will need her I would say this product is unreliable at best. If you only need one (but are willing to throw away money to pay for three) then get this one. But I won't do it again.
