    Design: Works well (hope they can also provide a 3/4" solenoid valve). Delivery: Needs to be improved (shipping out process), well-packed. Quality: Very good, solid, robust, operating voltage (3V to 4.2V) Service: Supplier is responsive and understands our requirements. I will recommend this supplier.
