I bought 5 but don't need all of them. Please make sure you're buying the right caddy for your model monitor. If you buy multiple I'll adjust shipping for only one charge if you let me invoice you.

From the manufacturer- 

"compatible with the Shogun, Ninja V, and all earlier Atomos monitor/recorder models. The Master Caddy II supports standard 2.5" SSDs and HDDs and features dual-key insertion (groove/slit on both sides) in contrast to the original Master Caddy's single-key insertion. The Master Caddy II replaces the original Master Caddy as the standard caddy for all Atomos monitors/recorders. (The original Master Caddy is not compatible with the Shogun.)"
