D'Addario Accessories Dexterity Band Finger Exerciser - Finger Exerciser & Hand Strengthener - Finger Strengthener for Strength & Dexterity - Finger Grip Strengthener Increases Speed & Fluidity

You will get your fourth finger to reach to the G violin string and with increasing strength. Also helps with guitar.

First off, I was really excited to see this product when it came out. It’s a great concept. Unfortunately, it is not very sturdy. I purchased 3 and 2 of them broke within the first hour of use. I was simply stretching my pinky and index fingers away from the other fingers back and forth. Nothing intense or that would cause friction. Save your money for a V2 when they make the elastic more durable. Quite the disappointment!

I tried few rubber-band styles and found this to be the most comfortable, most right sized (I have rather smaller hands than an average male) and most productive and effective hand strength exercise gadget for guitar fretting hand workouts. I recommend it. But...it only lasted 4 months before band broke (bought in late May - broke in early Sept). This is after light use - not daily, perhaps weekly at most. And the device was always kept in room temperature, handled with care and not stretched to a point of breakage. Do I recommend it still - yes for what it offers to you. But just be ready to throw it out in few months and buy another...then another...then another. I already bought 2 more.

At least for me, this is a pretty different type of finger exerciser than I’ve normally used otherwise. I’ve used countless types of the “squeezers”, both for hands and finger strength... But this goes a step further and is much more targeted to people that use finger dexterity in not a “normal” way (at least not me). You use this *when* you’re actually practicing and playing your guitar or similar instrument - and it works really well. When I first got it, it was much smaller than I expected (as in photo, tiny in my hand), but that isn’t a bad thing. In this case, it’s exactly how it should be. I also thought it looked and felt somewhat fragile, but 3 months later, and it’s still holding strong and has not lost any noticeable tension. I use it daily when practicing guitar. I shoot for about 15 minutes, minimum per hand (yes, I use it on both hands). If you’re a musician - or just someone that needs extra dexterity in their fingers, I would definitely recommend this.

Broke, ten minutes after opening.

I was surprised at how tiny and simple this thing is, and my initial thought was it couldn't be worth the price. But I was wrong. After playing with this for a few minutes I can definitely see how this will strengthen the fingers if used regularly for just part of your practice session. And it doesn't really cost much more than a set of guitar strings, so I think it IS worth the price. Once you've followed the instructions for putting it on once, you'll see how it goes on to and comes off of your fingers in mere seconds. Well designed with just the right amount of tension in the elastic, this seems like it would work for a wide range of hand sizes and playing styles. Recommended.

Not really ideal for beginner guitar players as you want good finger technique before you have something like this pulling your fingers together. Fine for warning up with some scales but not for playing music. Not really sure on feelings about this rubbing against the frets and strings. Nice in theory, not sure how much use it will get though.

Nice idea but it broke within a month of light use. Don't recommend it.

トレーニング用途に申し分ない品ですが、部屋のその辺に転がしておくという使い方には向かないようです。思ったよりも簡単にゴムバンドが切れてしまいます。 両手に着けようと 2 個目を買った直後に 1 つ壊れたので、3 つめを買うことになりました。ゴムバンドを傷めたりしないよう、着け外しは丁寧に行い、保管にも気を使った方が良いでしょう。 その後、また 1 つ壊れて、いま残りは 1 つだけです。取り扱いにはかなり注意が必要です。私は、この残り 1 つが壊れたら、そこで止めにするつもりです。

Excelente produto e serve perfeitamente para seu propósito.

The rubber band holding this thing together snapped after about an hour of usage.

I've played for years, self-taught so I developed some bad habits early on. One of which was my fingers lifting unnecessarily high off the fretboard which has always made playing faster runs more difficult than they need to be. The band kept my fingers from straying too far from the fretboard. As a result, scales and runs were immediately cleaner, in time & faster. I can see where the other reviewers are coming from - it seems quite easy to break if you're overstretching the band. I'll be sticking to chromatic runs with this gadget. It's a simple idea that works, if you want to iron out any flaws in your fretting hand technique I highly recommend this!

It was too soft for me.
