I finally picked up the Smallrig 1817 mounting plate to compare against the Kessler Kwik system I have used for years. I am a HUGE fan of Smallrig products and had hoped to switch. TLDR; I am not switching till Smallrig fixes some issues.

NOTE: It is taking YouTube a long time to get high-quality versions online. Sorry for the low res while they process.
