"The experience we had with Mr. Cool. was anything but cool! His website represented the wrong part for our Westerbeke engine and upon notifying him that the part would not work. He started listing off restocking fees, totally was rude and just a ****! He stated that when he received the part back that it needed to be repainted, if so that was exactly how he had sent it to us, now he's charging for that too! Over 10 days for him to process the credit which was over $100.00 less than any of his communications. BEWARE! We have pictures of his part listed and he is not an honest person, or one who takes responsibility for his errors.
