Neck and Shoulder Relaxer, Neck Stretcher Chiropractic Pillows for Pain Relief, Cervical Traction Device for Cervical Spine Alignment.

This is not just a bad product, it’s a dangerous product. This design is a ripoff from Denneroll and it misses a very important part of the design. The block does not allow you to rest the trapezius muscles like Denneroll does. At some point, even if you start off slow, your neck muscles will spasm. Continued use will give you an abnormal neck curvature, weak neck stabilisers and ligaments. You don’t want to take that chance with your neck. If you have loss of neck curvature, go for Denneroll and nothing else. It is the only product out there approved by the association of chiropractic professionals. Every single curve is meticulously designed for safety and effectiveness. My advise: Even trying this Wanida cervical block could really cost you. Don’t buy it.

this is good quality product and i feel very happy about this product ...daily twice a day i am using this product..
