Pros
Pro Adjustable resistance
You can adjust the resistance by turning the red button near the bottom end of the spring. The grip strengthener is adjustable from 22 lbs to 88 lbs.
Pro Very affordable
These are great entry-level grip strengtheners for just $10.99. There are options that cost several times this much.
Pro Simple anti-slip rubber handle
The rubber handle makes sure the grip strengthener does not slip out of your hand. The handle grip is rather flat with no finger nubs - so you can easily switch the grip techniques and change the amount of fingers you use.
Pro LCD display helps you keep track of your progress

Pro Pull-string for starting up
Gyroscopic wrist excercisers are often difficult to start up for beginners. A very precise and steady hand motion is needed. NSD Spinner comes with a pull-sting that helps you get the gyroscope spinning, so you don't have to spend time on starting it up(or learning how to do so).
Pro No vibration until you reach 15,000 RPM
For a regular user, 15,000 RPM is rather hard to reach. World records are a bit above that. This NSD Spinner has a very smooth gyroscopic rotor. You will probably work out at around 10,000 RPM and won't experience any vibration.
Pro Extremely fun
Compared to other fitness appliances, a gyroscopic spinner is very fun to use. It feels like a toy/game, which also lets you compete with friends for who gets the highest RPM.
Pro You can work out on the go
It's small and compact. You can carry it around and work out anywhere.
Cons
Con Spring might break
The spring that creates the resistance can break after a few months of use.
Con Not an option for advanced weight-lifters
Since this grip strengthener is adjustable only up to 88 lbs, then it works as an entry-level pick. More advanced weight-lifters will find themselves doing too many reps even with the maximum resistance.
