He was probably the best physics professor I've had at UCLA. He genuinely cared about his student's learning and that was really clear ever since the first week. He is a clear lecturer, but not the most engaging. He also spends a lot of time during lecture deriving equations but it would've been way more helpful if we actually did examples/sample problems in class. The midterms were really fair and the averages were pretty high both times. The final exam was easy too but it was open book and open notes, so the circumstances are a bit different. Overall though, I would recommend having him for any of the Physics 1 classes.
