Technical support

What we commit to after the instrument arrives, how an order is placed and paid for, what happens if something is wrong, and where the company actually is. Everything on this page is our published policy, not a summary of one.

What the service commits to

Six undertakings. They are deliberately specific, because "excellent after-sales" is not something a buyer can hold anyone to.

Mon – Sat, 09:00 – 12:00 and 13:30 – 18:00 (GMT+8)

01Installation and commissioningWe install and set up instruments for customers who need it, rather than handing over a box and a manual.
02Technical guidance from a personDedicated support staff answer questions about using a product over the platform — not a bot and not an FAQ.
03Spare parts guaranteedWe keep the repair parts for what we manufacture. An instrument that needs a nozzle, a handle or a board in three years is still serviceable.
04A dedicated after-sales deskRepair service is a named function with an owner, not something the sales team picks up between orders.
05Feedback that changes the productWe collect what customers say about build quality and act on it, and we answer letters, calls and complaints individually.
06Online support on working daysEnquiries, suggestions, complaints and faults are all handled online during the working week.

Manuals, wiring diagrams and firmware are sent on request — the download centre carries the software and the board blueprints, and anything else we will email you. Tell us the model or part number.

Buying guide

From choosing a channel to signing for the box — what to check, and when.

Payment and ordering

支付与帮助

01Choose the product line you want.
02Open a product line and a product. The detail page carries the enlarged photographs, the composition, dimensions, materials and the price.
03Use “Buy now” on the product to pick a channel: Taobao, Tmall or Alibaba. Enter the shop and either submit the order or keep browsing.
04If you keep browsing, you stay inside the same shop until you check out.
05At checkout, verify the delivery and billing address, the phone number, the contact name and the items.
06Choose a payment method and confirm.
07Your order is delivered by STO or SF Express.

Anything unclear at any point, contact customer service directly.

Dispatch and acceptance

发货与验收

Dispatch time

Dispatch time is how long the goods take to leave the warehouse and be ready to move.
“In stock” items are expected to ship the same day or the next working day.
Items with a longer lead time ship from the warehouse within a stated window — 3 to 7 working days, for example.
Laser engraving or personalisation adds preparation time, so the delivery date may move back.

On arrival

Before signing, check that the packaging is intact. If it is damaged you can refuse the delivery outright.
Once you have the goods, inspect the appearance first — no dents and no scratches is a pass.
Power on instruments and check the screen colour, look for dead pixels, and test the controls.
If everything checks out, confirm receipt. If you find a further problem, contact customer service for after-sales.

Invoices

发票相关

Note whether you need an invoice before you order — a remark on the order is enough, no separate request is required.

If the order has already shipped, contact customer service with the invoice title and the tax number. The invoice is sent once receipt is confirmed.

Companies and individuals engaged in business may obtain an invoice from us for goods or services paid for. The item name and the amount on an invoice cannot be altered on request.

After-sales

The two policies a buyer actually needs: returning something you did not want, and replacing something that failed.

7-day returns

退货政策

Within 7 days of signing for the goods, an unmarked product in undamaged packaging with all accessories present can be returned or exchanged with no reason given.

The product must be free of scratches, the packaging undamaged and the accessories complete, so that it can be sold again.
Return freight is at the customer's cost — unless the product itself is faulty, in which case we pay it.
The “three guarantees” apply as well: repair, replacement and return within these rules.

15-day exchange

换货政策

Within 15 days of the sale, a performance fault entitles you to an exchange or a repair.

On covered products, a non-human natural failure inside the 14-month warranty is replaced directly — you do not have to send the faulty unit back first. Customer service ships the new one for you to fit.
The product must be intact with all accessories and its box, or a repackaging charge may apply.
The exchange has to be made by the same person or account that bought it, with valid paperwork, or with customer service handling it for you.

Frequently asked questions

Anything else, email info@ycsmobiletools.com.

How do I place a bulk order?

Build a quote list from the catalogue and send it, or email your own spreadsheet — part numbers, Chinese names or a photograph of a worksheet all work. We reply with unit price, minimum order, packing and lead time for each line.

What does the warranty cover?

Instruments we manufacture carry a 14-month warranty. Within 15 days of the sale, a performance fault can be exchanged or repaired. After that, on covered products, a non-human natural failure inside the warranty is replaced directly: you do not send the faulty unit back first, we ship the replacement for you to fit.

Can I return something I do not want?

Yes, within 7 days of signing for it, with no reason required — provided the product is unmarked, the packaging is undamaged and the accessories are complete. Return freight is at your cost unless the product is faulty.

How fast do orders ship?

Items marked in stock are expected to ship the same day or the next working day. Items with a longer lead time leave the warehouse within a stated window, typically 3 to 7 working days. Laser engraving or personalisation adds preparation time. Delivery is by STO or SF Express.

Do you support OEM and ODM?

Yes. The group runs several brands for different market positions and takes on contract manufacturing, assembly and warehouse fulfilment for other companies as well as its own products. Send the specification and we will come back with a plan and a sample.

Can I buy a single unit, or become a distributor?

Both. Instruments can be shipped as a single sample before you commit to a container or an air shipment, and we take on platform distributors and channel distributors by product line — apply on the distributor page and we will come back with terms for your market.

A question the manual does not answer?

Send the model, the part number and what the bench is doing. We will tell you what to check first, or put you in touch with the person who built the board in it.
