Simple but effective

Does exactly what it says. The plastic feels sturdy enough, though I wish it came in different sizes for smaller fractional violins.

Easy to assemble

Took less than a minute to put together. My daughter loves using it because it makes her feel like she has a special gadget to help her play better.

Solid training aid

A practical accessory for anyone struggling with bow angle. It provides immediate tactile feedback when the bow starts to tilt.

Good concept, slightly bulky

It works well for practice sessions, but it adds a bit of weight to the bow tip. I wouldn't use it during a performance, just for training.

Great for my beginner student

This tool has been a game-changer for teaching proper bow hold. It snaps on easily and helps keep the bow straight without constant verbal reminders.

Helped fix my wrist tension

I had developed bad habits over the years. Using this trainer for 15 minutes a day has really helped relax my wrist and straighten my bow stroke.

5 FAQ

Q: Do I need any glue or tools to attach this?

A: No tools or glue are required. The device features a snap-on design that allows for easy assembly and disassembly in seconds.

Q: How long should I practice with this each day?

A: We suggest starting with 10-15 minutes daily to build muscle memory without causing fatigue. You can gradually increase time as your posture improves.

Q: Can I leave this on the bow while playing a song?

A: It is intended as a training aid for exercises and scales. We recommend removing it before performing pieces to ensure natural bow balance and sound production.

Q: Is the material safe for varnished bows?

A: Yes, the contact points are made of soft silicone that will not scratch or damage the varnish on your violin bow.

Q: Will this fit a 3/4 size violin bow?

A: This model is specifically designed for standard 4/4 full-size violin bows. For 3/4 sizes, the fit may be too loose to be effective.
