Have to reset the blocks after each start. Other than that they do the Job

Works. Simple as that.

very good beginner blocks...

Inexpensive but works for practice.

Used it for my Senior International Championship Games in Fort Myers, FL Dec 14, 2014. The BEST EVER, had other athlete borrow it.

My daughter is a high school multi-event high school track and field athlete and she and many of her teammates like this product. I actually purchased two, but wasn't sure if I should be so over zealous, but I'm very happy with the purchase. The items did not arrive as fast as others mention, but I imagine that's related to its increasing popularity and demand exceeding supply. None-the-less, they both eventually arrived packaged new and totally functional.

This starting block surpassed my expectations. It was affordable, well-built, and easy to use. Compared to similar starting block products, some in the $300-$400 range, it was a bargain at less than $70. Amazon delivered it at my doorstep with its usual efficiency, within 48 hours. I highly recommend it.

This product came in four days and was ready to go in ten minutes. A good set of blocks for both junior high and high school and college too. Have already had athletes use it hundreds of times and it's still going strong. Easily adjustable. Great set of blocks.

I haven't used this product yet but I'm sure it's okay my kids are going to learn how to use them because I now it's a big part of the sport once they get to high school and beyond so I'm just starting early.
