My friend brought this product to my house and I tested it, it was really great, I like the functions, on the other hand, balancing is a bit difficult I think when you have patience, the only thing i didn't like was that every time you picked up the phone you had to rebalance it and everything when you turned it back on i ordered one, the company that supplied it whipped him on my porch . and it broke I sent her another one again it was damaged on delivery so I canceled buying one I wouldn't do it. balance everything every time you use it
