Q-Pro preliminary course

Q-Pro products are marketed following a preliminary course carried out in physical presence with a Certified Q-Technology Tester.

This course includes the Perfect Posture Test, the tests necessary to identify the Q-Pro configuration corresponding to the Customer, the presentation of the offer and its main conditions as well as the possibility for the Customer to ask questions directly.

As part of this pre-contractual phase, the Certified Tester acts as an authorized intermediary of Q-Technology OÜ for the presentation and negotiation of the Q-Pro offer.

The Customer remains entirely free to make the purchase immediately, to postpone his decision or not to purchase.

When the subsequent order corresponds directly to the offer previously negotiated in person and the applicable legal conditions are met, its subsequent finalization on the Store does not constitute a contract concluded exclusively remotely. As well as the products associated with this order specifically.

Payment is due immediately at the time of ordering.

The accepted payment methods are listed on the Store at the time of payment and may include Visa, Mastercard, American Express, Apple Pay, Google Pay, PayPal, Shop Pay and other methods available depending on the Customer’s country.
