The quality of these devices is terrible. I tried both and they made an annoying noise that I could hear across the room as the dial turned. Some of the items you press to set the time did not move even when you pressed very hard. The switch on the side is very fiddly. The devices became warm after a few minutes of use with a low-power LED connected. Most of the good reviews on this must be fake. This is one of the cheapest feeling products I've ever had.
