The Simple 4 has in my work right away with the codes for Technisat and Sony. Good feel, very good lighting. You can turn on two devices such as satellite receivers and televisions through a single function, which is very convenient. The keys have a good feedback. Color do not like, but that's more a matter of taste. Unfortunately, the programming on the Internet did not work, it was absolutely not possible to sign up. But this feature is also very useful, will now contact to clarify once again to the hotline. It is necessary for me, but no longer, it has already worked with the codes.
