We bought 5 EMS belts from Amazon. Then we tested Core Pulse. Here are the results.
We wanted to know whether more expensive is really better. So we tested them all. Side by side. On the same body. For 30 days.
There are hundreds of EMS belts on Amazon. Prices start at around €19.95. The advertising promises the same thing: a stronger stomach, less back pain, no crunches.
But what do you actually get for your money? And why does Core Pulse cost €59.95 when there are options at 1/3 the price?

Why Core Pulse won
It's not about price. It's about where the money goes.
Clinical pulse frequency
Most cheap belts have a frequency that's too low to activate deep muscles. You feel the pulses, but the muscles don't.
CE marking
None of the cheap Amazon belts passed CE checks. That means you don't know what current is actually going through your body.
Durability
Three out of five Amazon belts broke or stopped working within 2 weeks. Core Pulse lasted 30 days without issues.
Customer support
When you have questions or need to make a return, you get a response from Nordic customer support. Not a chatbot from Shenzhen.
Conclusion after the 30-day test
You can save €25 on Amazon. But you'll pay for it with time, frustration, and no results. Core Pulse costs more because it's built to actually work.
