Review on Sierra International 18 7109 9 Marine Ring by Jake Hillyer

As a result of my tests, I determined that this item is not only useless but also detrimental to my cutting needs .The only pro i can THINK of is that it's made of metal. However, it does not effectively cut through tough materials rendering it absolutely useless. The cons are numerous, with the main one being the lack of performance. It is a waste of money and time. Industrial and Scientific shouldn't be associated with such an inferior product..
