Great product, easy to use
Works as described. Makes sanding panels a little easier

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

Made the deck refinishing smooth!
Used this to sand our IPE Decking. Glad I ordered. The sanding was easier than expected

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

Not a Forever tool but it gets the job done.
There are much nicer and much more expensive sanding blocks out there. This one was perfect for a job that required an almost disposable tool. If you are going to be working with a tool like this frequently I'd recommend spending a little more money and purchasing a nicer one. If you need a sanding block for a filthy job (fiberglass for instance) this will probably last long enough to complete the project and you won't feel bad for ruining it.

Flexible for smoothing shallow curves.
Works well for doing body work in prepping for paint.

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

Poor quality
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.

No son para trabajo duro
Compré 2 por qué las ocupo demasiado, se trabaja bien están muy lijeras, le doy 3 estrellas por qué ninguna de las 2 que compre duro, a la semana ya se habían aflojado los tornillos que sujetan la base de aluminio y el Velcro se comenzó a despegar casi al mismo tiempo
