This is an uncompensated comment. The quality of this product is obvious, the weight and action of the jackhammer are good indicators. A fairly strong push/pull force is required to open or close the contacts. Make sure you have a good anchor point. The clamps are heavy duty and hold the cable(s) very firmly, don't use too much wire and you'll get a solid, solid connection. Performance is excellent, on a normal sunny day my powerwall can generate over 60 amps especially during peak hours, I have temperature tested these switches and they average 80-90F (conditioned). I recommend this product. The prices are fair.
