I have gone to the chiropractor since I was a teen. Recently going every week. I have been able to manage 3 weeks without needing to go. These will not replace the visits but it will make the time between longer.
Shipping- no issues except the packing of the products. I got the wheel case and the wrap and they were shoved in between the wheels. The smallest one still has indents.
Wheels- I use each one for a few minutes and every time I get a crack out of my back, it’s great. I recently had a headache and as soon as my back cracked it went away. I will say that I am sore, I’m hoping it will go away with daily use.
