My fiance got this for me for Christmas I've been asking for something like this for months, so i'm still in the process of trying it but it's made very well, charges over night i can use it while walking around my house and it has a timer which is a plus.
I just received this in the mail. From what I can tell it is a very well made product and the instruction is easy to follow. Right now they have a 50% off sale which is a very good deal if you want to give it a try.
I will come back and update after a month to see how it goes.
