I have owned a number of switches, since I use this (autumn to spring) for connecting various lamps. The last had confused flashing display ads at once and no longer worked thus. I already had mechanical switches in use. However, these are limited and adjustable, so I had my experience, these are the times louder (mechanical monotone noise). These digital time switches I am very satisfied so far (about 1 month in use). The programming of the device is relatively simple and is well described in the manual. Class I find the built-in battery (the clock must be loaded only once for a few minutes before the first use). In battery assisted memory meißst the battery is empty, if you take draws the clock from the wall outlet, then you can change the battery only once and must programieren everything from scratch. Unfortunately, I have to deduct a star, because the delivered watch did not meet the current image, and I have chosen because of the image for the purchase of equipment (I a functioning clock identical to the current image have yet, and thus emanated from a same programming function ). But all in all I find the device - especially for the price - simply brilliant, and this can only recommend.
