I owned an older model that I wanted to take but became untraceable, the Logitech Harmony 525.C'était especially to retrieve on the Logitech website configuring the remote (that your settings will be registered on their site so no risk of loss). In fact I found the settings of this ancient pretty tedious remote. Well I just tell you that the software with this model is of unparalleled simplicity and intuitiveness, within the reach of a gamin.Certaines critics said that the touch located above the touchscreen were annoying and might to make unintentional manipulation by touching the screen. It has not yet happened to me after three days of use for the simple reason that the screen is configurable for a sleep between one and thirty seconds of inactivity on this one, (personally I settled ten seconds). We need to turn the screen sliding a finger from left to right or right to left, so impossible to reactivate it by manipulating the keys in the dessus.Javais afraid there not have enough buttons, no problem on the screen you will find everything you need and very rapidement.Après two days of trial and error all become very simple and intuitive for myself and the rest of the famille.Franchement I do not regret my purchase.
