Tripod tray ordered from Aliexpress arrived yesterday. (https://www.aliexpress.com/item/1005001793864931.html?spm=a2g0s.90423184.108.40.206284c4dv3RhVP)
Not too bad really, build quality seems perfectly fine. Although hard to go wrong when it's such a simple piece of gear
Had to use my own bolts/washers/nuts to secure it to my Panasonic lx-15 Nauticam Hosing, rather than the ones provided but that's not a big deal.
Perhaps one potential issue will be the 45 degree angle of the 1" ball arm connectors limiting how tight you can position the camera rig to the substrate. However, I'll need to give it test to confirm or deny this.
Looking forward to getting a chance to use this in the coming weeks.
