This agreement guarantees that:
- You will have the drawer for 7 days to evaluate it in real use.
- At the end, you decide : return it or keep it.
- If you decide to purchase it, we'll deduct the €39 shipping cost from your final purchase.

What happens at the end of the demo?
When we schedule the shipment of the crate for the 7-day trial, we will arrange with you both the delivery date to your center and the end of the usage period.
To keep things simple and straightforward , we ask that you confirm your purchase or return decision by sending an email to info@kinnxfitness.com within three calendar days of the end of the trial period.
If you decide to keep the crate, we'll complete the sale and invoice remotely (minus the €39 shipping cost), and it will become yours.
If you prefer to return it, we will arrange for collection on the agreed date, at no cost to you.
If we don't hear back within the specified timeframe and you don't request collection of the crate, we'll assume you're deciding to keep it and we'll proceed with the billing.
