Product review (5 stars): I appreciate being able to order these supplies from Amazon ...
I appreciate being able to order these supplies from Amazon and the Dampp-chaser system is worth the investment.  We have a mini-grand piano in our sanctuary that isn't air conditioned nor is it kept heated all week.  The Dampp-chaser system has really helped the piano keep it's tune.  Depending on the year, we had been tuning the piano 2-3 times a year.  Now we can go over a year between tunings.
