We document the numerical challenges we experienced estimating random-coecient Logit demand models introduced in the seminal work of Berry et al. (1995). We use two widely known datasets, various optimization algorithms, a large number of starting values, and dierent tolerances of the xed-point iterations to document such challenges. We show that the optimization algorithms converge at points where the rstand second-order optimality conditions fail. We also provide cases of convergence
