i've taken a lot of biotin and nothing worked. since taking this supplement I see my hair getting longer. Already reodered. Works

I just received this so I will update in about a month as to how it's working. It's very lightweight, love the fact that it has an on off switch and a light to show you it's on. I like the fact that it's quiet as I've had units before that make clicking noises which is annoying. I purchased this for our new house which we will be moving into in about a month, so I'm using it here until next week at which I'll take it there to get a head start in case the are any unwanted critters, lol. We have carpenter ants here like crazy as well as spiders so hopefully it drives them away. I will update at a later point to say how I feel it has performed.

I was looking for multiple practice tests to take for one of the subjects, and there was only one test for my subject in this book.
