We are not able to give success guarantees as every person is unique and experiences the effects differently. Some feel the positive effect very subtly while, for others, it has a substantial benefit. This has been shown in the research on strength using a dynamometer.
We guarantee all parts on the VivaZing® eclipse Flexible Strong plastic for 12 months, all other VivaZings® are guaranteed on all part for 24 months.
