Review: My power file gets used almost daily & I've always been frustrated at how quickly my previous belts would wear out & break. I've only been using these new belts for the past couple days & they are worth the money. They remove material much faster & with hardly any pressure needed.

*by D***N on 27 July 2022*

Fungerar extremt bra! Vanliga filbälten håller i kanske en minut om jag ska slipa ner en svetsfog, den här har hittills klarat av att slipa ner ca 40 cm svetsfog, plus två skruvskallar samt slipat skären till gräsklipparen
