Review: لا بأس به - لابأس به
Review: It's a Dspiae - As I suspected, it's a Dspiae (or at least the one desertcart delivered to me is). I'm old enough to remember when products from China (and Taiwan) were treated with disdain for being "Cheap & Nasty". Not so anymore, in my opinion. I already own one or two Dspiae products & they're more than satisfactory in terms of build quality & performance. I read multiple reviews of this little sander on multiple websites (mostly favourable). For me, as a plastic modeller, it's ideal, it really does get into places where conventional sanders can't reach. Another review mentioned that it cuts out when you apply any "real" pressure, but that's a documented design feature to protect the internal workings. The tool works just fine with gentle pressure & the appropriate grit. I found the "disco lights" a bit gimmicky & even distracting when working with magnification, but I can live with that. Sure, it's never going to replace conventional sanding methods & tools, but it's a welcome addition with some unique tricks!

### ⭐ poco practica
*by F***O on 25 July 2025*

muy bonita, aunque a nivel práctico no es de utilidad, además que el tamaño de la lija es muy pequeño y tienen poca efectividad, al ser un movimiento adelante-atras hace que se golpee muy facilmente en esquinas,la efectividad es comparable a usar una lima pequeña aunque mucho menor,no entiendo tan buenos comentarios...
