Wasn't sure if I would like this or not but I really do. We have the stand up version (not by same vendor) but really liking this smaller version that I was able to stand on edge and not take up valuable room on my side table. We used it for the outlet under the bed to the bedside table. Has enough power to run multiple items with no issues. I like that it comes with USB, C, 2 prong, 3 prong. I didn't use the included cover but that was because we had something else plugged into the other socket.
