Before revision:  If there are no search frictions, then there is a unique symmetric equilibrium in pure strategies, and the firms are not fully informative. With search frictions, the information a visit will reveal depends in a systematic way on the ex-ante probability that a firm's product is high quality.
After revision:  If there are no search frictions, then there is a unique symmetric equilibrium of this game, which, due to the countervailing incentives of attraction and persuasion, generates a payoff function for each firm that is linear in the information a visit will reveal depends in a systematic way on the ex-ante probability that a firm's product is high quality.
