Head-to-Head Specs
Here are the two plates side by side, from the Amazon US listings, completed from each maker’s page for the same model only where a listing is silent. A check mark shows the stronger spec on each line. Before you order either model, search the CPSC recall database: the U.S. Consumer Product Safety Commission lists vibration plate recalls and the fix offered. Mayo Clinic notes that research on whole-body vibration is still limited and advises checking with your doctor before you start, especially if you are pregnant or have a health condition. In a 2013 meta-analysis of randomized trials in healthy adults, programs of at least five weeks on a vibration platform improved knee extension strength and jump height.
