The aggregate ratings are sharply divided between one-star and four-star categories, with only a very small number of ratings overall. That gives little basis for predicting reliability or installation experience. Buyers should weigh this uncertainty alongside the need to confirm the breaker’s voltage and current fit for their particular circuit.
