• What is difference between Economical and Premium Versions?
    Economical line : Relatviely low cost cored motor applied, so price is lower than premium version. But, force is far weaker and has shorter lifespan comparing to premium lineup. (1/10 of Premium lineup lifespan)
    Premium line : Heavey duty coreless motor applied which means stronger force and much longer lifespan comparing to economical line. Design form factor is almost same, but stroke is slightly different. Please refer to the drawings of each version.
