You have to wiggle the wire to make contact but once my vehicle starts to move i lose contact very annoying

We installed the inverted backwards and after an array of sparks came from the battery the inverted no longer powered on

Id really like to see the fuses installed externally on the case for 50 it really doesnt seem like that much to ask to be able to service your unit yourself without having to desolder and solder in new fuses

I suppose if you pay attention and install the unit properly checking your connections with a multimeter before hand it would have worked fine out of the box
