Great Customer Service and follow up with order confirmation. Parts were shipped and arrived quickly with no issues. Will definitely continue to order from FS.

Very easy to use, just replace it and stick the tip into a connector and push. Effective to remove dusts or other stains. Great quality!

Cleans well, we were able to correct several issues with it so far.

Easy to use and does the job it is supposed to do.

Works as advertised and good value for the price. It can be replaced when it is used up and works well with my pen cleaner.
