There is no doubt that Rizer helps improve a persons ability!
Measuring Rizers reduction in force required to pull nails 
Over all average, Rizer reduced the strength to pull nails by 53.7%
In a series of engineering tests and experiments; the Rizer reduced the power to pull Nails by as much as 53.7%. That is close to “half” the strength required to pull nails! Translated to two times the pull when extracting Fasteners.
The Rizer user will experience a range of improvement/or challenge depending on a lot of factors: Density of the wood, type of wood, length and type of nails, how far they are driven as well as how long the nails have been in place. We cane attest to the fact that Rizer Hammer Helper will make nail pulling easier, period!
