My Marsa33 worked well in bench tests but sled testing releaved a possible power connection issue. Without question, John replied to my email in hours and said he would replace the unit AND is letting me return it to him in person and save me the shipping. He was very helpful before I bought the altimeter and continues to be nothing but supportive. Rockety continues to impress me with the feeling of community that everyone has.
