How mucc pounds of resistance is provided by one spring on each slot? What are the different weight levels of each slot is what im asking

There really isnt a simple answer to that man. The farther from the lever point you go, the more tension a single spring adds. This gets further complicated when you add multiple springs. adding/moving a spring can add anywhere from 10lbs to 200 lbs tension from what i have experienced. BTW, the average male grip strength is like 80-120 lbs

How to put springs on

The non-hinge side of the inner grip can be moved aside and slightly clear of the stop. Then you can move it toward the springs and easily put them on or adjust them. I call the hinged side the bottom, the stop is at the top.

Is it possible to buy or use different springs that are heavier or lighter?

As long as the new springs are the same size and can fit the hand grip, I think is posible.

Does this really work? Will it make your strength strong?

Yes, it's resistance training, but, it's a little harder to program than plate weights because it's springs. If you're already using free weights it'll make them easier to use. If you're using machines it'll train something you otherwise aren't. By themselves your grip should definitely improve, thought, you might not notice a size change. The change would likely be more in muscle recruitment and tendon strength. What it doesn't really do is transform you into popeye. That takes spinach.
