1. The hexagonal cut outs that run all along the handle are a bit sharp to the touch. Would feel a lot nicer to hold heavy cameras with this with bare hands if the edges all had a smooth rounded finish.
2. It is quite heavy. I would be much better if it was considerably lighter.
3. The material at the base, where you slot screws in to secure it to the top of a camera, compressed slightly where each screw was screwed in. I tightened everything down pretty tight to make sure it is sturdy and was not expecting this to affect the material at the base. It is probably fine, but it would be better if the base was stronger and would not be affected so noticeably after just one use.

Haven’t had an issue with the segments coming loose overtime. The wooden grip is great on ergonomics.

I'm having a lot of issues mounting with anything with Arri locating pins as pin holes are not deep enough. I'm not sure if the pins are too long but I don't have any problems mounting on other gear with Arri locating pins.
