@spatase I hope it helps him! Another tip; I was indecisive after 30 days, and reached out to them. They then extended the trial time (I can't remember... it was for at least two more weeks, maybe another 30 days.) The tricky part is it's supposed to take a while to work, so it can be hard to determine in that time. I found an FB group with people comparing notes that was also very helpful. For instance, start out with short sessions at low settings. And it really is key to clean your ear before use! Best of luck!
