Easy to conform
Conforms easy. Used it for fenders on a 1936 Chevy. The entire fender is round and this worked perfect. Get hook and loop paper. The extra piece used for psa doesn’t work that well

Grandson's X-mas gift. He loves that it can be used with either PSA or hook and loop paper.

Great for sanding curved panels
Love this for sanding bender board, it is a little cheap feeling but it was also priced cheap, wished it articulated a little more but it does most of my sanding on radiused wood panels

Update. Great sanding, semi-flexible longboard.
My original review was to complain that I didn't receive the stick & loop pad (or whatever it's called) with my sanding block, & thus, gave it only 2 stars. I apologize because I later found it stuck to the inner side of the box. So now I have, not only the replacement sanding longboard, but also the original one that I was supposed to return, for which I keep getting messages to return after all these months. I ask the company to please take payment for the second board. I haven't used these 2 longoards, but if I lover the nonflexivle boards, I know I will love these flexible version that I need to sand the very long body pannels on my El Camino.

Base plate is made of soft aluminium, used for approximately 2 - 3 hours and the the base plate has bent out of shape. Very poor design and material choice for what I once considered a reputable brand. Not impressed at all....

Exelente herramienta aunque pudiera estar un poco mejor en los acabados. Pero funcional.
