Review: 説明の写真に、80代ぐらいの高齢者写真が掲載されてるが、「これじゃあ無理じゃないの？」と思う。オモチャと考える強度では無い。高齢者リハビリとか、なんらかの原因で力が入りにくいとか言う方にも不適な気がする。しかし、特に指に嵌めるほうは、パッキン筋肉な人には弱いかと思うレベルではある。そういう中途半端なレベルなんで、中年の筋トレとかにはナガラで出来るレベルとも言える。自分は腕を痛めたリハビリに。高齢者では無いんで、ソコソコの強度で良い感じである。
Review: This is a great product and I’ve definitely noticed improvements in my grip and finger strength. I have always struggled opening jars and it’s shocking how much easier it is after a few hand exercises a day. The guide that comes with is very helpful!

## Questions & Answers

**Q: Are the three different colors different resistant levels and if so which color is which level?**
A: Yes, each color represents a different resistance level.  The light green color is the least resistance, the blue color is medium resistance and the orange color is the most resistance.  As an aside, I really like these hand/finger grip strengtheners because they are well made, easy to use and are handy to have when needed.  I use them every day and have noticed a tremendous improvement in the strength of both hands.

**Q: How about the quality of the finger exerciser, will it break? and how long have you been using it?**
A: Yes, they are very durable. This hand grip strengthener is recommended by my fitness trainers. I ordered it 3 times on Amazon last year, but they all broke in a week and some are expensive. Until I found them, their hand grip strengthener’s quality really good. It was 
similar to rubber bands, with very high elasticity. I have been using it for half a year, they still work, no break.

**Q: Will this help strenghten my very weak wrists? (I suffered severe sprains on both wrist they're "healed" now but still feel weak)**
A: You're better off training what connects and aids the wrist. Do farmers walks with dumbbells, a weight that you can barely hold for 30 seconds and walk with it until your hands drop it. Do 2 sets of this a week. The trick is for laziness and low tolerance for pain not to influence the drop, the hands must be the ones to drop the weight. It's also a great exercise for the entire body. You're welcome. Yes, this is 100% guaranteed to work and you'll see why the first time you attempt it.

**Q: Where is product made ?**
A: It says on the box Made in China.
