I didn't use this because as soon as I got it in the mail I realized this is for children - I thought it was for someone who is petite in size, myself being a height of 5'2. The description is very confusing. I spoke to 3 different Core Products representatives to return this- first 2 were nasty and monotone and wouldn't help me return it free of charge and send me a label. The 3rd person I spoke with was very nice and sent me a label. I gave 5 stars because of that one lovely representative.
