The answer regarding how long to use your device truly depends on each person. The recommended time is 10 minutes at the start and gradually work your way up from there. However, if your neck pain is in a severe stage, you may need to double, or even triple the time up to 15 minutes at a time. You should also consider at least a regular interval of 4 hours in between sessions and a rigid maximum of 15 minutes per session. As your condition improves and the pain and discomforts ease off, you can then reduce the frequency and duration of your stretch session. Please note that if the 15-minute stretch session causes you a headache, back discomfort, dizzy or nauseous sensation, then it’s best to cut down the time and readjust the pad so that it is more towards the middle of your neck.

Though, if your hamstrings are rather flexible, then 3 – 4 stretch sessions per week may be enough.
