I took the 33m model and I am satisfied with the product after a few days of use. However with 3,5bars pressure (house flow inside) it does not unfold completely I must help ... I will soon have a garden shed supplied with water at 7 bar. I hope the pressure will be sufficient to extend from the flexible advantage. All seems good even invoice must not pinch the pipe on the corner of a wall or other risk quickly make it unusable. The gun 8 jets functioning properly but seems fragile to therefore see in time. Practice the gun is provided with a small quarter turn valve for isolating the gun from the rest of the pipe.
