Tired of crackly phone calls when someone's online? These little filters are lifesavers! Just plug 'em between your wall jack and phone/fax machine. They block that annoying DSL interference so you can actually hear grandma clearly. Works with all brands and devices (except your modem - don't put it there!). Pack of 10 means you can fix every jack in the house. No tools needed - even your tech-challenged uncle could install these. Say goodbye to dropped calls and hello to actual conversations!
