What is your opinion of this product?
I really like the sound from this glass slide. Not too raspy or brash like the metal ones. However on e must be careful not to prop or let it fall on to a tile floor or it pretty much shatters and then you must buy another glass slide like I have had to do so many times thru the years. between having one in every guitar case and breaking a lot through the years I have bought dozens of these. but they do sound good and get the job done.
