It is one size larger than the ordinary water hose diameter and the water discharge from the nozzle has increased by nearly 1.5 times, and the efficiency has improved very much. The hose itself is also solid and firm and seems to be strong.
Because the interior is black, it is difficult to do so because the algae do not breed. Since it has a cord, it is strong against pressure, and it is currently used at 4 to 3 k. I guess it's a bit hard as it is a brand-new one, but I think it's tough. I will purchase it when it becomes unsatisfactory with the purchase amount this time.
