These apply to all our contracts for supplies and other services.


I. Purchase orders and contracts

All the contracts and/or agreements with our customers must be in writing.
We always reserve the right to accept a contract.
We will always confirm your order in writing.
This confirmation does not constitute a binding acceptance of your order.
Supplements and/or amendments shall be binding only if they are confirmed in writing by us.

The maximum order value must not exceed:

  • € 50,00 - goods mail (Warenpost) and
  • € 500,00 - DHL parcel

Our price list is non-binding. Orders and agreements for supplies and/or services are only binding if they are in writing. Our prices include the applicable VAT tax component.
Prices are for our goods only and do not include the cost of shipping.

Customer-specific quotes have a validity of 7 working days.


III. Payments

All payments must be made in advance.
Orders will only be shipped after your payment has been accredited to our account.
All goods remain our property until full payment is received.


IV. Warranty and Guarantee

The warranty is subject to the statutory regulations.
Liability for defects of goods lies with the manufacturer of the product and is 1 year, beginning with the date of receipt of the goods by the customer.
We guarantee the goods sold by us for 2 years for new goods and 1 year for second-hand goods, beginning with the date of receipt of the goods by the customer or his representative.
After delivery and receipt of the goods you have the right to have defective goods in the first instance rectified and, should this not be possible, to get the defective goods replaced by new goods.
By statutory regulations, you have the legal rights to a reduction in price or cancellation as well as to payment of damages.
Damage by wear is not covered by the warranty.


An important difference between guarantee and warranty is as follows:

Guarantee: ensures an unconditional compensation for damaged goods, given by the manufacturer usually for the duration of 1 year. In contrast to the warranty which is valid under the law, a guarantee is a promise voluntarily granted above the legal requirements that the goods or services are free of defects for a certain period of time.

Warranty: defines a temporary repair commitment only for defects which already existed at the time of the sale, given by the dealer for the duration of 2 years. Warranty is a legally arranged, that is, automatically applicable, strict liability for purchase or service contracts. The dealer is responsible for ensuring that the item or service at the time of delivery is free of faults.


A claim to guarantee and/or warranty shall be void if:

  • the product is not used for the specified purpose.
  • the goods are appropiately and/or falsely connected electrically and/or mechanically to other devices.
  • The housing of the goods has been opened and/or the seal attached to the housing of the product is damaged.
  • the goods show signs failure due to mechanically overstressing and/or thermal overheating.
  • the goods have been subjected to excessive environmental exposure beyond their rated protection class, which is IP 54 if not stated otherwise.


V. Right of Revocation

You can revoke your contract within 14 days without giving reasons in writing (eg, by letter or e-mail). The time limit begins after receipt of this notification in writing, but not before you have received the goods. Please note that if you return goods as parcel to notify us with the tracking nr so that we can assure a safe arrival of the returned goods. It does suffice if you send the goods or your written revocation-notice to:

Reinhard Mueller

Piusstr. 54

50823 Koeln



International customers outside the EU please note: In order to avoid taxes and custom fees being subtracted from your refund, highlite or underline the word 'returned goods' and indicate the value with '0,00'.


Consequences of your revocation:

In the case of an effective revocation the mutually received benefits or any benefits (eg interest )are to be returned . If you can not return the received goods in whole or in part only or in a deteriorated condition, you will be obliged to pay compensation.

With the surrender of goods this does not apply if the deterioration of the goods is only due to their examination as it would have been possible in a retail store.

You can avoid the obligation to pay compensation for a determination by the proper use of the product deterioration by not using the goods as your property and refraining from anything that affects the value of the goods.

Transportable goods are to be returned at your own risk. The cost of the return shipment lies with the customer. This includes all custom duties and clearance fees, if applicable.

Obligations to reimburse payments must be fulfilled within 30 days. The period begins for you when you send your cancellation or the goods, for us with their reception.

The right to revoke does not apply to:

  • goods which are manufactured to customer specifications
  • goods which are clearly tailored to personal needs
  • cables cut to custom lenght
  • B2B customers
