Foiltech guitar finger strength, piano and violin finger devices that power training device FA-10P

I'm a beginner violinist and this has been a great tool to train my hands.

I like it, my only complaints are that the weighting adjustment isn't very smooth. It's sort of confusing. Also the rubber piece that fits the palm falls off every single time I use it. Other than that it works

Great gadget for strengthening your fingers. Would recommend it.

Not sure it a return. My first Amazon return ever... i bought more then 1. dont extend it or use 5th finger. I think the picture is altered to make it look stabilized.

slightly goofy ergonomics, difficult to get consistent stiffnesses on each finger of the springs, some of the nuts on the backside must be spinning with the shaft. haven't taken it apart yet to try to fix it, have gotten it to work well enough thus far.

Works your fingers.

Despite the product description, this device is not useful for violin students. The grip is wrong and is not adjustable. Only a 4th finger is adjustable. Plus the distance between the 1st and 2nd fingers is incorrect. Did not include any instructions.

Muy buen artículo

Good build, good product to train 3/4 fingers

The product quality is ok.Every time I use it I have to be careful that I might not end up breaking it.The spring to change the weight is also not that effective.
