We bought 5 EMS belts from Amazon. Then we tested Core Pulse. Here’s the result.
We wanted to know whether more expensive is really better. So we tested them all. Side by side. Same body. 30 days.
There are hundreds of EMS belts on Amazon. Prices start at 149 DKK. The ad promises the same thing: stronger abs, less back pain, no sit-ups.
But what do you actually get for the money? And why does Core Pulse cost 442 DKK when there are alternatives at 1/3 of the price?
We bought 5 of Amazon’s best-selling EMS belts and tested them against Core Pulse for 30 days. Here’s what we found.

Why Core Pulse won
It’s not about the price. It’s about what the money goes toward.
Clinical pulse frequency
Most cheap belts have too low a frequency to activate the deep muscles. You feel the pulses, but the muscles don’t.
CE certification
None of the cheap Amazon belts passed CE testing. That means you don’t know what current is actually going through your body.
Durability
Three of five Amazon belts broke or stopped working within 2 weeks. Core Pulse lasted 30 days without problems.
Customer service
When you have questions or need to return it, you get a response from Scandinavian customer service. Not a chatbot from Shenzhen.
The conclusion after 30 days of testing
You can save 200 DKK on Amazon. But you pay for it with time, frustration, and no results. Core Pulse costs more because it’s built to actually work.
