I bought one to replace my L5 various remote controls: TV, DVD, internet box, DVD, ... The app Designer for remotes is really intuitive and the result is particularly convincing: fun, easy to use, ... Some features are particularly useful, such as macros. For example, just by clicking a button, turn on the TV, the box, the receiver, positioned on the amp on the right channel, and it opens a panel allowing me to drive the box (the box which provides me the necessary TV). And in 1 click, I close everything. Same for the DVD, with a panel suitable for the DVD. In short, I am extremely satisfied with the product. Got something to change? Yes: to facilitate the creation of macro relying on other remote controls defined in the L5. For a macro can now be defined only from the same remote control buttons. It is then necessary merger or the buttons on the remote control, define macros, and then delete unnecessary buttons (macro does not need buttons defining it). I would also highlight the support, just incredible. My amp is a Atoll, a fairly confidential builder, delivered without remote control (optional ...) and remotely controllable, with very little information to program a universal remote. Despite extensive research, I have never managed to get the Pronto Hex codes. Out of spite, I contacted the L5 carrier. Wow! How to say it? They took care of everything, have done the research, offered me several remote controls were always very quick to respond (in the day), always trying to satisfy my needs. Inatendue a surprise! This is the first time I see such a carrier involved. In short, you guessed it: do not hesitate, great product and great support!
