Seems to be right for the price but the parts all feel like a one week use and you'll notice it's not as good as it use to be. Thankfully I'm not remodeling and am just using this to patch up some walls around the house. I believe I have seen this brand at dollar stores around but would probably be about the same price.

Easy to securely attach sandpaper compared to other blocks I have. Surface is not perfectly smooth which I'm hoping won't cause problems on automotive surfaces.

A little bulky but fine if you have big hands.

Good product, easy to use at a very price.

Measures 8.5 x 16cm

I like the size but one side of the sandpaper holding mecanism is loose. It works but probably won't last too long.
