Snug body hugging design allows a targeted massage, providing quick relief to pains on neck, shoulder and upper back, more effective than kneading/shiatsu massagers or vibrating/percussion massagers. 18 different massage programs and 9 intensity levels to suit your needs. Suitable for all family members. The knob on the back can change the distance (5.9"-9.1") between the two tapping modules. You can adjust the massager to massage hard-to-reach areas, or for different family members to use. During massaging, the product generates moderate amount of heat to help metabolism and blood circulation, yet it should be still considered as a manipulation product. One 15-minute session is sufficient to relax muscles and hence ease tiredness and tension. The product has the 15-minute auto shut-off feature for convenience. Overload protection system ensures product durability. The overload protection system may shut off the machine due to motor overheating, unstable power supply, abnormal touch force, etc. When this happens, the massager will be locked off for 1 hour before it can be turned on again. Premium breathable PU leather. Designed for great comfort and easy cleaning.
