This is a great alternative to building a full on work bench. The plastic is extremely durable and sturdy, and as long as you have wood to use, it saved me lots of money! I loved that I could adjust the bench to fit where I wanted it to in my garage.  I added a peg board to the back, and it's extremely functional.

Pros: Great value, easy to assemble, able to adjust size to fit your needs
Cons: none!
