Is it possible to use the RF extender to remote control RF devices like a ceiling fan?

And for those who have a TSU3000, The side buttons CH-, CH+, VOL+, Vol- etc... They look suspiciously like the very poor (easily breakable) NEO hard buttons directly under the NEO's LCD screen. Please tell me if they appear to be made from the same plastic.

Thanks in advance for any info.
