Experiences

In their own words.

12 women helped shape it, from the first conversation to the prototype. This is what they said.

Before and after

First a promise. Then two weeks.

What they promised themselves, and what they noticed after two weeks with the pendant.

Her promise
A participant writes her promise on a card. Only hands and the card, no face.
After two weeks
15–20 s, subtitled, sound on tap. The same woman as on day 1. Question: ‘What did you notice after two weeks?’ Record after the home test with the first testers. Name and age on screen (with consent).

Word for word, from the recordings.

Recording

Delft, 2026

“Then I'd wear it every day. It's jewellery too.”

Prototype session participant

“Other people can see a light too, but a little buzz is just for you.”

Prototype session participant

“This is something you don't have to look for. You can't lose it either, because it hangs round your neck.”

Prototype session participant

“Here it's one single thing. Really just one. One thing. But a very important thing.”

Prototype session participant

“I think it would help me, because it's really on my body”

Online session participant

“But you do it all in such a friendly way, and I'm fine with that.”

Prototype session participant

“With some products you have to figure it out, but this is crystal clear”

Jeweller, on the battery instructions

Critical too

What wasn't right yet.

We don't leave out the criticism. This is what they said, and what we do with it.

“But I can hear it too, can't I?”

Prototype session participant

The prototype made a sound when it vibrated. The real pendant should only be felt.

“This is too fragile, this is too thin. Especially with 5 grams on it, it'll break in no time.”

Jeweller

That's why we recommend a sturdier chain than the prototype's.

“Because it's a deal with myself.”
