Oh the humidity!</FONT></DIV> <DIV><FONT size=2 face=Arial></FONT> </DIV> <DIV><FONT size=2 face=Arial></FONT> </DIV> <DIV><FONT size=2 face=Arial>I did happen to look at their prices and they were asking about $37.50 per kilogram, and they recommended 2 per average piano...then they suggested replacing them yearly.  So, $75 - 80/yr is a good little expense, especially if it works marginally at best.</FONT></DIV> <DIV><FONT size=2 face=Arial></FONT> </DIV> <DIV><FONT size=2 face=Arial>I would be inclined to say no on this product too, except maybe in special cases such as Paul mentioned.</FONT></DIV> <DIV><FONT size=2 face=Arial></FONT> </DIV> <DIV><FONT size=2 face=Arial>Thanks for your input.</FONT></DIV> <DIV><FONT size=2 face=Arial>  </FONT></DIV> <DIV>Richard W.

As far as I can tell there is no scientific data that demonstrates its effectiveness. I used to run a dehumidifier in my shop, and I would empty a gallon of water out of that thing every couple of days even when the humidity was only moderate (55%-65%). If Musicsorb did what it claimed, after several weeks of humid weather the piano would burst apart from the pressure of all those expanded silica pellets! <BR><BR>Ryan Sowers<BR><BR> <DIV class=gmail_quote>On Sun, Feb 12, 2012 at 11:31 AM, Richard W.
