D’Addario Varigrip Hand Exerciser–Improve Dexterity and Strength in Fingers, Hands, Forearms- Adjust Tension Per Finger– Simulated Strings Help Develop Calluses- Comfortable Conditioning

Definitely helps to buildup strength in your fingers, and I like the added feature of being able to build up the calluses on the finger tips. Very well made, and the price was reasonable.Recommended!

I have to admit I do like this, in fact I love it. I think it's brilliant. It's well built, and it's clear D'Addario have put some real thought into it's practicality and how it'll benefit your guitar playing. This isn't a corporate fad designed to milk money out of novice guitar players who might think they need every single guitar accessory on the face of this planet. (The experienced ones I know who have been playing for over a decade also found this useful in their own way and considered getting one themselves.)The packaging it comes in (a card with the exerciser affixed to it) has a list on the back of all the different exercises you could essentially incorporate, ranging from building finger calluses to strengthening muscles and training them for bar chords.I started using this every day, playing around with it and giving the muscles a good flexing which I began to reap the benefits of. I could hold chords for longer and the fingers felt more agile when finger-picking. The callus builder (located underneath the grey strip seen in the picture) I was initially skeptical of, since it's "string simulator" is three lines that somewhat represent the thinner strings, but they're more raised groves in the plastic body as opposed to real guitar strings which I feel would have been better, or metal at the least.Nevertheless, they do show promise, and the fingertips feel toughened. The ability to change the tension on each finger press (via turning the small dials for each) allows me to slowly improve the strength in the little fingers while stepping it up for the main three which are much stronger (of course, as they said too, favouring certain fingers isn't ideal.)It fits into the pocket nicely and works great as a warm up before an intense session, or in your spare time when you know there's something you need to work on. It's versatile, strong and definitely serves me well. Highly recommended, espcially for a tenner.

This is a useful device for strengthening your grip. The pressure you have to exert on each finger is considerable, so I think that some people with weaker grips may find it difficult to push the pins down. The little finger in particular is difficult, as each pin has equal tension. Frequent use should help there, as that's the point of the exerciser.The moulded base that is supposed to simulate strings is not much use, as it doesn't simulate the feel of real guitar stings as you would press them on a guitar fretboard. You won't develop the toughness in the tips of your fingers, which you will get from real guitar practice, from using this item.Also, the adjustment cogs do not make any real difference to the tension in my experience.Overall, I recommend this product for the basic tension and comfort in using. However, I cannot give full marks to a product that doesn't deliver on all its stated claims.

This is AMAZING! I am a beginner bassist and this is really helping me to strengthen my ring and small fingers, also good for speed too. Not only that, you flip the rubber piece over to the other side and it really helps you to build the calluses. This is seriously one of the best items I have bought on Amazon. I have it on my desk so whilst working or in meetings I just exercise my fingers. I highly recommend the Varigrip hand exerciser !

Delivered very quickly, well made and very good value for money.I have only used it for a few days and I am already feeling the difference in my grip strength!

Exactly as described. A very versatile training tool for fingers on stringed instruments

It looks and feels well made. It performs quite well in a number of configurations, and it all depends on what you expect from it.I was a bit disappointed that the tension was as strong as it is at it's weakest setting - this makes it difficult to use as a practise aid for finger co-ordination - for example for finger picking guitar or trumpet etc. Weaker springs would have made this much easier, and tension could be increased if desired. I bought the varigrip mainly to exercise my fingers at the onset of arthritis, and I'm not sure that it will actually help. This is mainly because it is difficult to use the grip to bend specific finger joints enough, and I now also have my doubts about strength exercises actually easing the symptoms of arthritis anyway. No doubt the grip will improve the strength of fingers, hand and wrist, if that's what you want.

I decided to try this pack of the strengthened and dexterity tool, as I have lost some due to health issues and thought it may help improve my guitar playing.The design of the strengthened seemed quite well thought out as can be held in a variety of different grips and difficulty can be adjusted. It also offered a fingertip conditioner to keep calluses. The Fiddilink dexterity tool is pretty basic just some interlock plastic discs. I have now used both items regularly for quite a few weeks and these are my results.Strength tool.I have not noticed any improvement in things like bar chords, where I hoped to see a difference. Possibly this would have more impact on a very new player, with developing control of little finger, but I have not noticed any improvement in mine but this could be due to health issues. The callous tool is not practical, it does not really work, just some plastic ridges which have made no difference to my fingertips.The fiddilink.Just a fidget gizmo, I did not find any dexterity improvement, again possibly different for completely new guitar players.These are of course sold as aids for when you are way from guitar, but if you are going to try I would say they are more for those completely new to guitar not existing players, as I have not gained anything from them.
