We bought 5 EMS belts from Amazon. Then we tested Core Pulse. Here are the results.
We wanted to know whether more expensive really is better. So we tested them all. Side by side. Same body. 30 days.
There are hundreds of EMS belts on Amazon. Prices start at 199 kr. The ads promise the same thing: stronger abs, less back pain, no sit-ups.
But what do you actually get for your money? And why does Core Pulse cost 599 kr when there are alternatives for 1/3 of the price?

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 a frequency that’s too low to activate the deep muscles. You feel the pulse, but the muscles don’t.
CE certification
No cheap Amazon belts passed the CE check. That means you don’t know what current is actually running through your body.
Durability
Three 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 return it, you get a response from a Swedish support team. Not a chatbot from Shenzhen.
The conclusion after 30 days of testing
You can save 250 kr on Amazon. But you pay for it with time, frustration, and no results. Core Pulse costs more because it’s built to actually work.
