Question: Can Thumper be used with Massage Oils or Lotions?

Question: Is there any maintenance required for Thumper?

Question: Why does the Thumper get warm?

If the temperature does exceed normal limits, Temperature Overload Protection may activate, shutting the machine down. You will need to let it cool before continuing use.

Question: How do I clean Thumper?
Answer: If the external surfaces become soiled, wipe clean with a cloth dampened with a mild soap.

Question: How does Thumper compare to other massagers on the market?
Answer: Thumper is the only massager that goes after muscle tension with percussive action. Ordinary massagers exert their force in a horizontal direction and do nothing more than "rub" your skin. Thumper directs the action of its anatomically positioned massage spheres vertically-downwards into your muscles. You feel Thumper throughout your body, not just on the skin surface.

Question: Does Thumper have attachments?
Answer: No attachments are needed with Thumper. Its massage spheres are positioned to let you treat all areas effectively.

Question: Does Thumper Itch?
Answer: Because Thumper does not "rub" the skin, itching does not usually occur. Itching may appear, however, under the following conditions:

- if one has poor circulation
- if irritable material or clothing is used between Thumper and the skin (Ex. Synthetic materials)
- if left in one spot too long (this is due to increased circulation)
- if the relative humidity of the atmosphere is quite low

Question: Does Thumper 'kickback' energy/vibration to the handle?
Answer: Thumper has very little 'kickback' to the operator. Not like many other vibrators.

Question: What can I do if I find Thumper uncomfortable on one area?
Answer: Thumper was designed to be strong and effective with all muscle groups. For sensitive areas, place a folded towel between Thumper and the area being massaged.
