One of my all time favorite glass slide. It is great that Dunlop provides the measurements right on the package. Makes it a lot easier to shop for their slides. It's amazing how many "custom" slide makers don't provide the length, inside and outside diameter.
ThE slide works just as it should. Sounds very good even on electric and acoustic guitars. I recommend this one to anyone searching for a good glass slide.
This 215 is a bit longer then other manufacturer slides which is good if you want to reach across all the strings.
I buy their other slides as well, which are about the same size but gyou must check for actual dimensions before buying.
PROS
cost effective
clear and accurate measurements/specs
the perfect size for me
good weight - very light
CONS
Nothing bad to say about this product. If you drop it it can break easily, so keep the plastic box to protect the slide from breaking
As always Dunlop slides are the way to go - affordable with great quality, fit and finish. Nice warm tone without much string noise. Highly recommended for a working musician - once you get use to it you will never want to use another one.
