I bought this slide to try out on electric guitar, as I have never had a 'real' slide before, only using cut up beer bottles in the past.
The quality of the slide is excellent, it came well packaged and protected and the glass is thick, well finished, with no sharp points or visible imperfections.
I have fairly small hands and this fits on both my ring and little finger well. As with all glass slides you have to be careful with them as they can break easily but this feels well made and constructed to last a long time.
The tone the slides produces is clear and strong, I use it both in a traditional blues setting and for more experimental music with lots of effects (Similar to an E-bow).
Would definitely recommend to other players.
