Fotga flexible gear ring belt for Follow Focus Follow Focus FF 46 mm to 110 mm DP500II DP500IIS DP500III JTZ DP30

Did what it said and was good quality. The connection with the clip and to the camera was sturdy. And worked well with my follow focus. Would recommend.

Excellent quality, little expensive but the rest are still expensive as well, making this one somewhat good value, very flexible unlike the ones that come with video gear like neewer follow focus etc, this one's really nice

Inexpensive and reasonable quality. Worked very well with my gimbal follow focus monitor.

Slipped and only sort of fitted the cogs. Ditched it.
