TIP15-day delivery via Aliexpress Standard Shipping

For this product, Aliexpress Standard Shipping is available with guaranteed delivery within 15 days. It’s the most reliable delivery method and, in most cases, it’s handled by a courier company. The 15-day delivery is something we actually tested.

When you order from a Chinese warehouse, AliExpress adds a customs fee to your cart of about €3,70 per order. When you receive the package, you don’t pay anything extra.

Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

SJCAM SJ4000 Air: 4K resolution, slow-motion and 4x zoom

A big advantage of action cameras is their compact size. That’s also true for the model SJCAM SJ4000 Air, which measures only 29.8 x 59.2 x 41 mm. The entire camera weighs just 35 grams. It is also water-resistant up to five meters (with the included case, it can be submerged up to 30 meters).

In the package you’ll find a 4K sensor, complemented by 30 fps recording with the H.264, 2,0″ codec, a wide viewing angle of up to 170°, as well as 4x digital zoom. Among the recording modes, we can mention slow-motion, time-lapse, or loop recording. You can store your data on a microSD card, up to 64 GB.

It also offers excellent connectivity thanks to support for 2.4 GHz Wi‑Fi connection. The manufacturer also thought about linking it with your smartphone via a mobile app, and the microUSB connector takes care of charging. The built-in battery is 900 mAh. You can also use the camera in dashcam mode or as a webcam for video calls.
