I received my Polaris with astro attachment. WiFi version. The materials, fit and finish are great, but I have gripes about the design. The main two-axis Polaris has a clamp that orients the slot on the lens axis, so forget using any custom fit camera plates and L-brackets without using a secondary plate (or using a piggyback clamp). The second issue is both the main clamp and astro clamp to don't open wide enough to work with any slightly oversize dovetails. My Smallrig L bracket for my Z6 fits, my Smallrig L bracket for my Lumix G9 doesn't.
The software is nearly unusable, and I expect months of updates and fixes to do much of what is promised reliably. Also, the app has next to no controls when you don't connect the Polaris to a camera. There are a couple of "joystick" controls that move the head verrrrrry slowly, and that's it.
I was thinking the knobs would allow you to use Polaris as a precision 2 or 3 axis head. Not really. Precision heads provide clutches so you can quickly get a rough alignment. There are no clutches on Polaris, and the movement is so fine that you'll grow old and gray just adjusting the head tens of degrees.
I was unable to format a Samsung SD card (card is required) I put in my Polaris. Now I'll need to find out what cards people are having luck with. There's a Facebook Group that the Polaris team post on every so often. I thought I'd check to see what threads were active here.
