## Customer Reviews

### ⭐⭐⭐⭐⭐ Does its job
*by T***G on December 9, 2024*

We ordered this for a commercial installation involving drilling into a concrete pad. It worked well and did what it was supposed to do

### ⭐⭐⭐⭐⭐ Trabajo
*by J***R on August 1, 2022*

Es bueno funciona muy bien pero si es poco pesado y el cepillo donde absorbe el polvo es muy frágil se rompe muy fácil

### ⭐⭐⭐⭐⭐ Better than all the dust extraction devices out there
*by I***L on April 10, 2022*
