Good quality - worth buying

For just under 30.- an original remote control? The formerly much more expensive. The function is perfect, it's also a Originale.Gut, the old man had only kept well over 4 years, then the moisture problem was there (was here already often described). I have this problem then unfortunately, despite the good advice can not resolve here. For 30.- for a new remote control I have over it but not annoyed, not even over the relatively short shelf life. But no one must also change if you re anschafft an original operation.
