We are proud to offer international shipping services that currently operate in over 200 countries and islands worldwide. Nothing means more to us than bringing our customers great value and service. We will continue to grow to meet the needs of all our customers, delivering a service beyond all expectation anywhere in the world.
How do you ship packages?
Packages from our warehouse in China will be shipped by ePacket or EMS depending on the weight and size of the product. Packages shipped from our US warehouse are shipped through USPS.
Do you ship worldwide?
Yes. We provide free shipping to over 200 countries around the world. However, there are some locations we are unable to ship to. If you happen to be located in one of those countries we will contact you.
What about customs?
We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Do you provide tracking information?
Yes, you will receive an email once your order ships that contains your tracking information. If you haven’t received tracking info within 5 days, please contact us.
My tracking says "no information available at the moment".
For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.
Will my items be sent in one package?
For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you have specified combined shipping.
If you have any other questions, please contact us and we will do our best to help you out.
Refunds & returns policy
Order cancellation
All orders can be cancelled until they are shipped. If your order has been paid and you need to make a change or cancel an order, you must contact us within 12 hours. Once the packaging and shipping process has started, it can no longer be cancelled.

Your satisfaction is our #1 priority. Therefore, you can request a refund or reshipment for ordered products if:

We do not issue the refund if:
- Your order does not arrive due to factors within your control (e.g. providing the wrong shipping address)

Посылка пришла быстро. Терморегуляторы соответствуют описанию. Однако, согласно номеру посылки вместо терморегуляторов должны быть регуляторы оборотов двигателей постоянного тока, которых в этой посылке не оказалось. Если они придут в другой посылке, то я претензий иметь не буду.

Спасибо за отзыв! Рекомендуем уточнить у продавца статус регуляторов оборотов. Если они придут отдельно, проблема будет решена.

Customer –
Bad. I didn’t received items first time refund after 3 months because package not shipped more than 2 months they kept me waiting 90 days. Second time seller cancelled order prior delivery day 24hr as he is unable to ship my order third time this package received unprotected was open and closed by transparent tape 2 times was missed. No refund this is there solution. As tracking shows delivered (whole package not items). So pay first and pray next. Where is buyer protection. Why I have received my package open by whom. This is my experience. If seller interested I can support him with video recording from Time I received. Should be someone responsible for such think.

trip point is saved so that memory is retained when power is cycled. relay turns on as temperature goes up. this will not work if you want to control a heater.

Thank you for your comment! You can set the module to “heating mode” (P0: H) to control a heater. Let us know if you need help!
