For the moment the maximum width supported is 9mm, so if your smartphone + case are within that range then yes. We are working on a solution for a larger width for you to have access to a variety of cases.
While every product we make comes with a 1-year warranty, we do not offer returns on items received as Kickstarter rewards.
Vixari Tripod was born through Kickstarter and the support of the community is what allows our business to design new products and bring them to life. Supporting a campaign on Kickstarter and getting a reward is a different process than buying a product directly.
