Very happy with this product. I bought 3 of it so I could use them on different parts of my equipment.
One on my camera cage, and 2 on the cage of my Odyssey 7Q+ monitor.
It comes with 2 different sets of screws so you can use it almost anywhere. The holes pre-drilled in the chassis of it can make it fit almost anywhere. The space between the holes are standard so that you will always find a place to screw it onto.
The little allen key comes with it. It's really a full kit and for this price I was positively surprised.
The 31,8mm Arri type rosette is perfectly shaped. I bought 3 of them, all of them where perfectly finished. No problem for fitting the rosette with other products from other brands included.
Le little phillips screw that you use for tightening the rosette onto the metal chassis are feeling strong as well. They even give you an extra one, in case you need a replacement.
I used these products a couple of times already and so far so good. I'm glad Smallrig offers professional quality products at a reasonable prices. It's definitely a brand I will keep in mind next time I'll need to rig some stuffs on my gear.
It features light weight and small size. It could be mounted with Arri rosette handle on the one end, and then mounted on QR plate or cage via threaded holes on the other end. Its functions cannot be underestimated and I really like its creative design! Quite good!
