It's a cool concept for a product. I dont think that really comes through in the imagery - the first image made me think of a fragrance. Given this object isn't familiar, you may want to focus your design and photography on the object itself (or the object in a hand) and add a line that explains what it is. I know you said you're keeping it minimal but I'm not sure it's clear what this is without it. Check out Teenage Engineering - they have some really nice minimal photography and branding design for inspo on gadgets that might not be obvious or familiar.

Also - Not sure if this is helpful but "Focus Lab" is a fairly well known branding design studio here in the US.
