We would like to point out that only the devices listed on this page can be purchased if no attempt has been made to repair them. Unfortunately, we have no use for control units with accident, transport or water damage or units destroyed by improper opening. Please note that we will return such equipment to you with our shipping and handling charges. If your device does not show any of these previous damages and you are interested in selling your used device to us, please send us your device. We will check it first and then immediately send you the agreed amount by bank transfer.
If the purchase should be rejected after examination by us, for other reasons than those specified above, you receive your equipment back free of charge. In order to process your purchase, we need your contact details and bank details. Please fill out the purchase form, print it out and send it to us together with your device.
If you are a trader, please enclose a corresponding invoice with VAT. This is a prerequisite for our transfer to you.
Please also note our packaging tips.
