I've been using this for a while now with a Sony a7Riii as well as a Canon 6D MKii with no problems. I particularly like the interesting Allen key holder with integrated magnet. I haven't lost the hex wrench yet, and have also been able to loosen and tighten many of the cage screws with ease without having to remove the tools. My only minor complaint is that the handle is a bit short. My hands are usually about the size of an XL glove, so someone with big hands will probably find this too short. Yes they have an extension cord but for $50 it's not worth it IMO. I also have a monitor adapter that works easily with a 7" 4K monitor. Being able to quickly remove the grip saves time and doesn't worry about losing screws. Overall I'm happy with it and for mine Hand size a little tight, but other than that, I highly recommend it!
