Price was right but if they don't do what they are supposed to do, it doesn't worse paying a penny. I have one that I bought at dollar shop. So, I know how it supposed to work. These must have been sitting in the storage too long. I will try silicon spray to revive the dead rubber tips. But I shouldn't have to do this to make this thing work. I'll do it because it would be cheaper than sending them back. Very unsatisfied with the product.
