The overall quality of the product is good. It is made of good materials and well thought out. If you're just looking for a motorized slider, this is a smart buy. However, if you're buying a YC Onion slider to pair with a DJI Ronin gimbal, there are a few things to keep in mind. You must purchase a YC Onion Interlink controller and NP-F550 battery to install and power your Ronin. 2) The YC Onion application needs some work (v1.2.1 at the time of writing this review). I was able to control the hot dog motor through the app after a firmware update. However, I could not control my Ronin-S via the app. Although I was able to search for and connect to Ronin, I couldn't open the UI. That's the main argument for the slider for me. I'm sure they'll fix this issue, but until they do you might want to put off buying a YC Onion motorized slider. I plan to post a video review once I resolve my DJI controller issues.
