Very good quality product, very well finished and perfectly designed. Very well packaged on delivery. No unpleasant surprises as the measurements taken were accurately followed. Installation went smoothly, carried out by a competent professional who did a careful and meticulous job. The gate automation was completed smoothly thanks to a reinforced area designed to accommodate the fixing of the motor arms, maintaining the aesthetics without compromising on strength. The end result is very satisfactory, very attractive and inspires confidence. Congratulations to the designers and manufacturer.
