Review on 3M Sanding Block 2 75 Inch 5 25 Inch by James Cypert

As other reviews have stated, this sanding block is practically not recommended. It's made of lightweight plastic, relies on four small plastic pins to hold the unit together during use, and is in no way contoured to fit the hand. I've found that the block doesn't stay together unless I glue it on. Connection on both sides of the block (adhesive tape). It's too easy, too immaterial to do any serious work, requiring too much energy and attention to do a good job. Maybe for modelers, but I don't see it used anywhere else: I would definitely suggest a different sanding block.
