Summary: We consider modal logics of products of neighborhood frames and prove that for any pair $$\mathsf{L}$$ and $$\mathsf{L}'$$ of logics from set $$\{\mathsf{S4}, \mathsf{D4}, \mathsf{D},\mathsf{T}\}$$ modal logic of products of $$\mathsf{L}$$-neighborhood frames and $$\mathsf{L}'$$-neighborhood frames is the fusion of $$\mathsf{L}$$ and $$\mathsf{L}'$$.
