Spot on voltage
Compact design is like an inch long! Definitely simplifies installing in tight spots. Thought heat might be an issue but remains cool in my application

Stay alert if you use this!
I usually buy the DROC brand. Amazon was out, so I ordered this. I installed it between a 4 volt LED outdoor security light and a 12 volt battery. After about 5 minutes, the unit actually got so hot, it melted ! Never again !

Worked for about 3 days,
And during that 3 days I thought it would be a good solution and bought 2 more. We'll see about the other 2.
