Anyone use or own the ~$35 bluetooth keyboard cases for the Note 2014? I would love to get one of the fancy belkin ones but the price is way high. I have a Bluetooth keyboard and mouse I use for SMS/MMS and productivity apps at school but its not very practical because its not attached so it gets clumsy. I could easily ditch the mouse if those things are worth a darn. I saw some good reviews but wanted to see if anyone here has had good luck with them.
