Im looking for best mouting/tripod for Osmo Mobile 2. Maybe manfrotto. Max to 100$ Any ideas?

I bought the PIXI EVO 2-Section Mini Tripod and have been happy with it. The second position allows you to make the base even wider when you want good stability.

And it's well within your price range.

The only caveat I have: don't try to use it with the DJI Extension stick. While you can set it up this way, it's not really rigid enough when the Extension stick is fully extended. I'd go for a standard photo tripod if you're trying to get some height on it.

Hi, thanks for reaching DJI Forum. We do appreciate bringing this query to us. KIndly click the link below for a better understanding about our tripod. Thank you.

Osmo Tripod

Sirui T-005X Traveler Ultralight....  I've had one for about 5 years, and without question the best photo tripod I've owned ( and I have Manfrotto's, Gitzo's and Vortex's as well ).  It's perfect for any of the Osmo's.

I remove the standard ball head (which is of high quality in itself ) and use the (reversible) mounting screw and attache DJI's Articulating Locking Arm for Osmo (DJCPZM00279)  The following review gives a good description, but also go to the SIRUI website.  Links below are to adorma.com and B&H, but can be found on eBay and Amazon.  FWIW, the B&H has it on sale for $79... all others are at $99.   Worth it at either price.

Finally, I purchased mine for use with a Sony NEX-7 with some substantial glass.  Although lightweight, it was very stable with this heavier equipment.  With the OSMO's light weight, it's very solid.

I suggest "Vikerer Triple cold shoe mount" on amazon.com

the heavier the better. the dji stand is also pretty good for flat surfaces.
