Review: Buenos por el precio - Son discos que sirven muy bien para el desbaste, como indican vienen en diferentes granos, se consumen de forma regular, duran lo que tienen que durar, lo que único negativo que veo es que suelta mucho grano de los flaps, si sueltan pero este en especial suelta un poco más, no es excesivo pero si suelta.
Review: Seems fine - The new Tooliom (TL-250M) welder did not work and the warranty is completely worthless so I never got to use them :(

### ⭐⭐⭐⭐ Seems fine

### ⭐⭐⭐⭐⭐ Works Well. Decent Longevity. Great Value
*by R***. on 28 January 2023*

Purchased these for "coping" baseboard inside corners. Novice DIYer. Saw a video using an angle grinder instead of a coping saw to do this. Was worried about my ability to control the angle grinder sufficiently to get decent results. No issue at all. Much easier to control than I expected. and the learning curve short. The result was better and quicker than what the coping saw could do. I've used a single 40 grit disk to cope inside corners on about 300' total baseboards. Better longevity than I was expecting.
