Main Features:
The Flanger FA - 10 Extend-O-Grip is designed for all instrumentalists, from beginners to professionals

Use the Extend-O-Grip to warm up before playing and to strengthen and stretch the fingers.

Our unique ergonomic design allows you to exercise the fingers, wrists and forearms while practicing the correct action for playing musical instruments.

Increases finger speed, strength and independence.The span between fingers can be extended and strengthened by progressively shifting the fourth button away from the others.

Practice without your instrument anywhere, anytime: compact and ultra-light design means you can carry the Extend-O-Grip in your pocket, bag or instrument case.

Hold the Extend-O-Grip in either hand and place your finger-tips on the tops of the buttons. Push the buttons down independently or all at once. The fourth button can be moved away from the others to extend the span.

    Flanger Grip Strength Trainer
    Excellent tool for building up finger strength, very much useful for musicians, as well as just people wanting strong and nimble fingers. Packed in a well-designed protective translucent packaging, the back lists some tips and suggestions for use. There are three different tensions available. Very lightweight, the device's shell is mostly plastic and pleasant to the touch, the lower part and the finger pads are soft, smooth and rubbery, making it highly ergonomic and comfortable to use.
    Other devices similar to this one are available, though usually significantly more expensive, while being the same in quality and performance. The price point combined with excellent build quality makes this Flanger device a worthy alternative to the grip trainers sold at your local musical store. Unique to the Extend-O-Grip when compared to the competition, is the fourth button being possible to move further away, in order to extend the span. This is an fantastic product and fully worth the low price, highly recommended
    This is not a negative, but unless you are an experienced musician with considerable finger strength, I do not recommend getting the Medium tension (black) one, as you might find it to be very stiff. Beginners should start out with either Very Light (yellow) or Light (green) tension, then build up accordingly. If you are serious about building up grip strength, getting all three might be a good and quite affordable option, especially considering the great price at Gearbest.
