Previously had the premium version 8155-20 in use. (26.52) After a light frost destroyed the closing mechanism, I have, unwisely, that part 8108-20 risen. I throw now after 1 season of the vexing in the bin. Reason: 1) The closing mechanism under the handle dissolves immediately at the slightest touch. One can not hold properly without the locking mechanism disengages the rod. Complete Fehlkonstruktion! 2.) During the irrigation action mechanism causes in the handle such noises that I hardly dared me to pour after 22 clock my garden, so as not to wake the dear neighbors. I now again to 8155-20 risen and am very satisfied.
