OP/Tech vs CUFF Peak Design for Sony RX100 M7

The OP/Tech (€13)is much more comfortable, cheaper, lightweight, and discreet. 

On the other hand, the Cuff (€39,99) feels more secure; the chance of breakage is close to zero. However, the neoprene of the OP/Tech also stretches a bit and feels more conformable, so I decided to keep the Op/Tech.

Ah, the OP/Tech is compatible also with other OP/Tech products such as the Compact Sling
