ABC Bow Corrector Violin 4/4-1/2

It is very easy to fit and remove but stays firmly in place. I have used it on violins from 1/4 to full size and it works very well. It forces students with inconsistent bowing to bow at right angles to the strings in the one spot - not up and down the strings - and hence produce a better sound. It is the type of product you might lend to a student for a while, so having 2 or 3 on hand, if you have a few beginners, would be helpful. I strongly recommend this product.

I am a beginner and using this for a few months has had a very noticeable effect on my bowing. I am very satisfied with the quality and the ease of use of this product and would recommend it.

Even for a more advanced player to revisit the straight bow from time to time- allows easy adjustment to play closer to the bridge, which is why I chose this model; works well on cello and violin.

The bow does not easily pass through the opening and gives scratching sound. Not at all happy with the product..

Great little helper when you start to play the violin.

I am really surprised of how much it can help my little students to move correctly the right hand. It can do wonders for the beginner players.
