What Our Customers Have to Say About Our Service
This is not some placeholder text generated by AI, this is real people saying real things.

“Hearing that the SMMC1 with it’s original ruby cantilever and stylus is in good condition is absolutely fantastic news. I was scarred it would require a new stylus which would have destroyed the whole idea of it being an SMMC1!”

“If I haven’t had an opportunity to use this Optical Inspection Service, I would be listening to my crooked AT-OC9XML for many more hours wondering is this it? Now I have a new replacement cartridge that sounds great!”

Our shop is based in Lithuania, Europe. Since the cartridge is a small device, shipping it Worldwide is not a problem.
Then shipping process is slightly more complex. We will provide you with a Proforma Invoice, which you must include alongside the appropriate customs form (CN22 or CN23, depending on the item’s value). In the “Category of goods” section of the customs form, please specify “OTHER: For inspection (not for sale)”. By following these steps, the items will enter the European Union as a temporary import, thereby avoiding import duties and import VAT.
This is a temporary measure. At the moment, we are unable to calculate the shipping price during checkout. Instead of adding this uncertainty to our service price or inflating the shipping cost, we will update the outbound shipping price after checkout. This process typically takes about one business day.
This is a temporary notice. You will soon receive a notification with your exact Outbound Shipping Price and this notification will change to ‘Your Shipping Price was Updated”.
It’s usually within ±25% of the preliminary price. However, certain shipping zones in Europe and the United States, such as islands or remote areas, may incur significantly higher costs.
Preliminary Outbound Shipping prices are set only for the European Union and the United States. However, you can still place an order, and we will contact you with the exact shipping price for your location.
The client is responsible for shipping the item to us and ensuring its safe arrival (Inbound Shipping). When shipping from outside the EU, the client must provide the appropriate customs declaration form for temporary import. Failure to do so may result in the shipment being declined to avoid incurring import taxes. Once we accept delivery, we take responsibility for handling the item with care and for shipping it back to the client (Outbound Shipping). All return shipments will be marked as “returned goods” to ensure that the client will not incur any import taxes. All return shipments will also be insured for the value specified in the order.
This is not strictly necessary; you can enter zero euros. However, if the package is lost during return shipping, the maximum compensation you can receive is the standard mail coverage, which is approximately 80 euros. This is standard for all courier services.
Shipping insurance with UPS costs 1% of the declared value and is already included in the checkout calculation.
