Review on 📸 Neewer Quick Shoe Plate Adapter with 1/4 3/8 inch Screws for DSLR Camera Camcorder Tripod Monopod, Compatible with Manfrotto 501HDV 503HDV 701HDV 577/519/561/Q5 - Aluminum Alloy by Lequon Kirkpatrick

I didn't like that these included plates weren't compatible with all other Manfrotto style 501/501 plates I had. The shoe adapter/receiver will fit Manfrotto plates, but genuine Manfrotto quick release adapters will not fit Neewer plates. Not sure if this was just my issue, but FYI the plate that came with the adapter may not fit your existing quick release mechanisms.
