I really like the design of this charger (mostly because I can still use/look at my phone while it's charging at night, if I have to. However, there are little things that are very annoying. One is that the blue light that shows you your phone is being charged is quite bright and annoying. I've seen another reviewer say they covered it with tape, but it's still a "problem" that people should be aware of. Next, there is an issue with it consistently charging my phone. I have an X in a case and my girlfriend has an 8 in a case (both cases are compatible), but we have to set our phones down on it a certain way or they won't charge. Again, this isn't a huge deal, but when your product only has one thing it's supposed to do and it sometimes doesn't even do that, then it's worth mentioning.
