This relay has compatibility and durability is satisfactory. I feel that the accuracy is not inferior to that of the same type of certain manufacturer. And the performance in terms of cost is Pikaichi. Because of the structure of the machine, it becomes a consumable item because of frequent exchange This price is very appreciated.
