I hesitated before ordering this universal remote control by having fear it is a gadget that does not work or a ridiculous battery life makes the rapidly unusable. My fears proved unfounded: the battery life is excellent, the synchronization with the iPad was no problem and the recognition of the equipment was very good too (only my stereo was not in the database data). The iPad application that goes with it is simple to use and very complete. Only flat (little surprise): take the time to set everything right (especially when one of the devices is not recognized, and to do it learn each key). In short, I am pleased with this purchase and would recommend.
