Broadlink RM Pro info please

Hi

Seen these units -
http://www.ibroadlink.com/rm/

with the accompanying app -
https://itunes.apple.com/es/app/broadlink-e-control/id793152994?l=en&mt=8

Are they any good? Are there any potential security issues I should be aware of?

Are there better units?

Thanks
