No quality issues. I used theses to supply 30 amps to the circuit. I have 4 identical circuits so I only needed 8 relays; 4 for positive and 4 for negative. I must have full power and ground isolation when not in use. Very easy to solder and use. They supply 12v at 30 amps x 4 circuits or 120 amps total. Works very well. These repeats can be physically interlocked so they can be easily connected together. Note. The relay coils each draw about 150mA.
