Query: Is it safe?

I like the basic idea of the super pole, but the way the horizontal bar has to be moved is a bit scary. It is very unstable during adjustment and I am afraid it could cause a fall and an injury, which is exactly what it is supposed to prevent. I'm not yet sure, but I think I will be returning this pole. Also, when I first received it pieces were missing. I called the manufacturer and they were rude and impatient with me and refused to send the parts. I finally had to call Amazon to get the parts I needed even to set it up!
