CHERRY B.UNLIMITED 3.0 Review @ Vortez
 

The B.UNLIMITED 3.0 is aimed at the office, appealing to customers who want a reliable keyboard backed by German build quality and well-thought out design. The B.UNLIMITED features an incredibly low-profile design, a 128-bit AES encrypted wireless connection, for complete peace of mind, handy shortcut buttons and built-in Ni-MH batteries. You may also be surprised to find that this keyboard doesn’t use their own Cherry MX key switches, but instead uses a membrane SX key.
