It's subtle and helps the hand to naturally conform to proper bow hold.

She has had a good hold with it from the start.

I've developed a good bow hold!

I am stickler about proper bow hold

They also notice that the position of their fingers is changing while they are playing and are forced to adjust to the proper hold

I have been playing for about 4 months and instantly fell into an easy comfortable bow hold.

Works almost like an "alarm" for improper bow holds

Has instantly improved my bow hold, improved my bow pressure control.....these are GREAT!!!!

Now she starts with the proper hold, and she adjusts the hold if the bow little by little slips towards her fingertips

My instructor was shocked at how good my hold was not long after I started using this while practicing.

Using this product helped my daughter to stand up her pinkie and get the more proper bow hold.

almost every one of my students i’ve let borrow it had a perfect hold nearly immediately.

Right the way my kids were forced to have more proper bow hold
