What E-Fit is
E-Fit International is based in Budapest and sells in the United States through Electro Fitness USA. The range includes the wireless Infinity system, which controls up to ten units, and a Lightwear line that is pitched for home use. E-Fit claims more than 2,500 studios in over 60 countries.[1]
Regulatory record
The FDA database lists K133225 for the E-Fit EF-1280, decided in 2014, and K202148 for the E-Fit Infinity, decided in 2021, both under the applicant Fit-Pro Kft.[3] An FDA comparison table describes the older EF-1280 as a cabled, prescription-only system with 12 channels, 5 to 120 Hz and 100 to 500 microseconds.[2]
How you buy it
There are no prices on the website. E-Fit advertises “$0 Down, 100% Financing” and starts with a discovery call and a demonstration. If you run a studio, ask for the total cost over the financing term and compare it with a public rental model such as VisionBody Pro’s.
Who should buy it
Studio owners who want a wireless multi-client system and are comfortable with financing. Home users get more transparency from the home suits in our ranking.
