Are the three different colors different resistant levels and if so which color is which level?

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.

How about the quality of the finger exerciser, will it break? and how long have you been using it?

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.

Will this help strenghten my very weak wrists? (I suffered severe sprains on both wrist they're "healed" now but still feel weak)

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.
