Each Keen can only be used on one hand and cannot sense both hands at the same time.  If your unwanted gestures involve both hands and you order two Keens, we recommend starting with just one Keen to get used to it before wearing your second.  During this time, some people who buy two Keens find by wearing one the other hand naturally learns to reduce its behavior.  Other people who think they need just one Keen find that their other hand starts to take over and so they need two.  Each person has their own unique experience with Keen.   

If you do buy two Keens, you can receive a $30 discount if you order from our website and use code SETOF2 during checkout.  And we have a 90-day return policy on orders from our website so you will have time to learn what works best for you.
