Not as well made compared to US made/hardware store. Edited, seller offered a refund
I have been buying and using ground rod clamps for decades. I don't feel like I over tighten this clamp and certainly didn't tighten more than the one I was replacing. Before I was at a point I thought it was tight enough, it snapped. Metal is thin and looks porous. The seller reached out to me and offered a full refund even though two were in a pack and one broke. I accepted half refund.

Fits 5/8, doesn't fit 3/4
Fits up to 5/8", will not fit 3/4" rod. Description "Great for 1/2" to 3/4" Grounding Rod..." is inaccurate.

Tamaño ideal
La pieza se ve de buen material, el tamaño es perfecto para lo que la necesitaba (la puse para sujeción de varilla de tierra física ) quedó excelente y tiene buena presión en la tuerca. Al cable lo presiona bien y al momento no he tenido problemas.
