Good product, good value for money. Well finished. Working well. This one is without the acrylic shell but with 4 bolts-nuts. Note that the input and output values can be calibrated (select the value, push right button>5s, release, push shortly and quickly many times the right button to increase or left button to decrease, save by pushing right button >5s, release to get back to normal display).
AAA
