Bests & Worsts Reviews from Amazon

I constantly fight to stand up straight so I thought this would be a great solution. I read the bad review saying it works off blue tooth and they couldn't figure it out. I am no computer programmer but I have the basic knowledge how to connect things. Problem is If you have a question and want to text them you have to sign up for a service called intercom a minimum of $49 monthly service that you will probably never use again. Furthermore the endless amount of stick pads you will have to buy since it only comes with a few to get you started. I find this product not as good as it should be for the $107 shipped price.
