Product as described, works well As you bend, you arch your back vibrates so that You correct the posture, it surprised me for good and makes you go well straighten

Thank you store, quickly sent! Delivery to St. Petersburg 9 days! Here comes discharged!

It meets the promised looks good quality and vibrates strong by not maintaining posture

Days came in only four. shipping much faster.

It took about 2 weeks to arrive, very fast, the product comes complete and in good condition, fully satisfied!

Good product although it lacks better performance, it is not able to differentiate when one is inclined to buckle the shoes even though the back is right for example.
