  • Relieve your pain by using the TENS Mode.
    • TENS is a non-invasive, drug free method to control your pain by sending tiny electrical impulses through the skin to target the nerves. In many cases, this stimulation will greatly reduce or eliminate pain.
  • Strengthen your muscles by using the EMS Mode.
    • EMS is widely used in hospitals and sports clinics to treat muscle injuries, to re-educate paralyzed muscles, and to prevent atrophy in affected muscles.

Product Specifications:
  • 2 EMS Modes:
    • Synchronous: Stimulation of both channels occurs synchronously. The "ON" time including "Ramp Up" and "Ramp Down" time. Therefore, the setting of ON Time should be no less than two times of the "Ramp" time in this mode. ON TIME Ramp up + Ramp down
    • Alternate: The stimulation of CH2 will occur after the 1st contraction of CH1 is completed. In this mode, the setting of ON Time should be no less than two times of the "Ramp" time. The OFF Time should be equal to, or more than, the ON Time. ON TIME Ramp up + Ramp down OFF TIME ON.
  • 5 TENS Modes:
    • Burst Mode (B): Burst rate: Adjustable, 0-5 5Hz; Pulse width adjustable, 50~300uS; Frequency fixed = 100 Hz
    • Normal Mode (N): The pulse rate and pulse width are adjustable. It generates continuous stimulation based on the setting value.
    • Modulation (M) mode is a combination of pulse rate and pulse width modulation. The pulse rate and width are automatically varied in a cycle pattern. The pulse width is decreased by 50% from its original setting in 0.5 second, then the pulse rate is decreased by 50% from its original setting in 0.5 second. Total cycle time is 1 second. In this mode, pulse rate(2-150Hz) and pulse width(50-300S) are fully adjustable.
    • The SD1 (Strength-Duration) mode consists of automatic modulation intensity and pulse width in 40% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 40% while the pulse width is increased by 40% in 5 seconds. In the next 5 seconds, the intensity is increased by 40% while the pulse width is decreased by 40%. Total cycle time is 10 seconds. Pulse rate(from 2~150Hz) and pulse width (from 50~300S) are fully adjustable.
    • The SD2 (Strength-Duration) mode consists of automatic modulation intensity and pulse width in 70% range. The intensity is always increasing while the pulse width is decreasing and vice-versa. The intensity is decreased by 70% while the pulse width is increased by 70% in 5 seconds. In the next 5 seconds, the intensity is increased by 70% while the pulse width is decreased by 70%.

Quality
Color: Missouri Tigers, Size: Large
So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.

May Pose Choking Risk
Color: Mississippi State Bulldogs, Size: Standard
As far as the puzzle aspect my dog was not interested but it did entertain him as a chew toy and the base held up pretty good. Take note though, the brown blocks come right off and may pose a choking risk.
