Saves the day!!
I am so glad i listened to the Crutchfield Advisor who recommended i get this to help me balance the weight of the arm on my Pro-Ject Debut Carbon Esprit. it really does help put the final touches on making sure the arm is perfectly balanced. NOTE: Once you figure out the weight of the arm/stylus then you need to determine which setting to use on the Shure (there are two place settings for the stylus) - There are videos on YouTube that help you figure this part out.
Pros: inexpensive Simple and very easy to use Effective tool for measuring stylus tracking forces
Cons: The slide for the weight is a little loose - could be more precise but locking into grooves
