TERMS: You must contact us in two days and be prepared to remit full payment within 7 days. When the shipping charges are indicated, they are for FEDEX ground. If you require other type of shipping, we will charge the actual shipping charges plus $ 20. For items that are guaranteed, the buyer has three days from receiving to test them and contact us if they do not work as described. If the buyer continue using an item that he/she is claiming to be exchanged, the guarantee will be voided. If an item that is guaranteed does not work properly, we will replace or fix it. Only if we cannot replace or fix the non-working item, the bid money will be returned. In this case, fees paid for the transaction (shipping, ebay, PAYPAL) will be discounted from the amount to be returned. We will arrange with the buyer the best conditions to exchange the non-working item or return the buyer's money. Buyer pays all shipments and insurance for item's refund or exchange. Shipment charges are not returned under any circumstance. All items are insured when shipped. We try to provide accurate information of the items for sale and answer emails queries as soon as possible. Bidders should ask questions before buying. ITEMS THAT ARE NOT SPECIFICALLY GUARANTEED, ARE SOLD AS IS. Unless specifically indicated, instruments are not tested beyond what is described. We are very interested in the buyer satisfaction as shown by our feedback reports, and will work with the buyer to solve any problem. As with all used equipment and devices, it is the buyer responsibility to have this item completely checked out by a qualified technician before it is used or its results relied upon.
