Popp Z-Wave KFOB Remote Control
Vesternet mistakenly shipped me the Popp Z-Wave KFOB Remote Control instead of the Aeotec Key Fob I'd ordered. After I contacted support, they sent the correct item two days later and let me keep the wrong one.

Aeon Labs Aeotec Z-Wave Key Fob Remote
I bought the Aeon Labs Aeotec Z-Wave Key Fob Remote from Vesternet for S$69, alongside the Minimote; locally it's S$90 at Automate Asia. It's similar to the Minimote but more portable, designed to clip onto your keys.
