Terms & conditions

The following T&C apply to Motion Analysis products developed and sold by STT Systems (ie, 3DMA suite, 2DMA suite and iSen), and the accessories related to these products. Please note that all T&C below apply to your purchase unless otherwise specified in the proforma invoice, which may tailor some of the T&C to your specific project.

Purchase terms and conditions

Payment terms

Unless otherwise stated on the proforma invoice or official invoice, 100% of the amount is due with the acceptance of the Quotation and issuing of the Purchase Order.

Delivery time

In normal conditions, most items are shipped within 2-3 weeks after reception of the Purchase Order and Payment. Please note that the transit time must be considered separately and may vary considerably depending on the final destination and shipping service selected.


STT may offer on-site installation and training services. However, no on-site installation and/or training is included unless openly stated in the formal documents. A limited remote assistance for the installation is included.


Prices are based on costs and conditions existing on the date when the Quotation is issued, and are subject to change by the Seller before acceptance of the Purchase Order.


Both 3DMA and iSen software licenses are controlled by a security dongle (also known as hardware key), which is delivered with the system. This dongle needs to be plugged to the computer where the application is to be executed. IMPORTANT NOTE: In case of dongle malfunction or breakage, users can ship the damaged dangle to STT and then purchase a replacement. The software license will then be linked to the new dongle. This operation is not extended to cases of loss or theft of the dongle. To all effects, missing a dongle is equivalent to missing the license.


Limited Warranty

A warranty period of one year is granted for all elements included. This periods starts on the date when the goods are received by the customer. During the limited warranty period, and upon proof of purchase (in the form of product registration or packing slip / invoice), this product will be repaired or replaced at our option, without charge. The end date of the warranty period will remain the same after the repair or replacement.

Repair Policy
