I have very dry hands and sometimes the EWIs touch sensors don respond right. Any tips?
This was more of a problem with the original model EWIs and EVIs. Newer models have greatly improved this. If you have tried adjusting the Key Sensitivity knob on the EWI and still have trouble with the sensors not sensing your fingers you might try a hand lotion with a high Glycerin count. Corn Huskers Lotion or KY seems to work well. Look at the ingredients and notice if Glycerin is the first one listed. Nyle Steiner recommends rubbing a couple of drops of glycerin (available at most drug stores) into the fingertips. We have also used a little ChapStick on the fingertips with great success.
