Sometimes some of the features are difficult to find. It is most difficult to edit the videos. The recording can be complicated to do because sometimes you can hear the click of the button when you press stop. This makes the video seem unprofessional.
Also, when trying to edit a video, you want to rewatch it in totality very often to see the changes. In order to watch the clip in totality, you have to preview it. It would be better to just be able to watch the clip in parts like it is possible to do in iMovie. Further, when you do preview it, the buffering takes a LONG time. Even when the video is about 2 minutes long, it takes a long time to load. This prevents you from making progress quickly.
