Sterling relays stand out for their sturdiness and connectivity (gold-plated M6 or M8 nuts, depending on the model, ensure that there will be no problem running the relay's power rating on cables of appropriate cross-section). It's also worth noting that the Sterling relay range is completely waterproof (IP68).
