Hand Grip Power Gauge (0~130KG)

Pros: funny thing, and with memory functionality ! ! ! This means it actualy keeps memory of the maximum measure. With the red button under the Gauge you reset it.

Cons: The gauge after 85 Kgr didn't worked, and not only that, after two three tries the gauge started from +4 Kgr :( :( :(
Also, it is for right-handed.
finally watch out your skin, it could be caught as mine

Other: little bit disappointing that worked at about 60 %.

Pros: Benefits:
Very cheap these products
Good construction quality for the price
Saved a lot of time
Maximum of relatively high force
Most useful !!!!( I use it every morning)
Later use and the results can be seen in part to strengthen the hand of a significant

Cons: Weaknesses:
The initial use of the dial (at least by me) went six pounds and stayed there forever.
Left hand very inconvenient to use the device.
If a large power users have pain afterwards

Other: Mandatory in every home!

Pros: Fun, nice to measure your grip and compete with friends. Mechanically simple, ff something breaks is not that complicated to open it, understand how it works and put everything in place. Cheap!

Cons: Very cheap built material Mechanically impossible to measure more than about 85kg, if you open and look at the mechanism you will see why, so the description is wrong, measures up to 85kg.

Other: Intersting, hard to find, funny. Not for professional use of course. Nice to have for 4.49.
