Success story of Aliexpress is based on seller oriented business model. They are promoting sellers to sell in their platform. Most of these sellers will have zero customer service, including a bunch of fraudulent businesses. I have been buying at Aliexpress for about six years with mixed experience. Among thousands of dollars spent on Aliexpress, I've been scammed about 10% of my purchases. Each time, the Aliexpress has backed the seller. This model is not a sustainable one. For the last one year, I switched my regular business to Amazon, and I am very happy with the switch. I pay more at amazon, but, always satisfied. I still shop occasionally at Aliexpress, but, only when I do not find the item at Amazon. I am pretty sure many others will eventually switch to Amazon or other customer focused businesses. After all, customers are the center point of a business, if you do not satisfy your customers, they will find someone else who are better at serving their customers. Let me give few examples -
(Example 1) - Recently, I purchased a battery charger. The seller shipped me an European round pin plug with the charger that is not compatible in North America. All I demanded is seller send me an appropriate flat pin plug that works in the North America. Seller refused to send a plug. I raised a dispute to Aliexpress, and Aliexpress thinks, I do not have enough evidence to support my claim. So, refused to support my case.
Example 2 - In bought a phone that is defective as the wireless charging function was not working. So, I raised a dispute, Aliexpress asked me to ship the phone back at my own expense. Canadian shipping cost is high, and a tracked a shipping to china would cost more than the phone. So, I shipped the defective phone without a tracking number. Unfortunately, seller never acknowledged the receipt of the shipment and I lost the whole cost of phone plus shipping.
Example 3 - I ordered 500 pieces of custom printed pens with laser light. The package arrived with half of the products with dead batteries, a fifth of the products were damaged. Raised a dispute, and the Aliexpress verdict went in favor of the seller.
In conclusion, I would review Aliexpress shopping experience as a hit or miss. If you are lucky, you might get a good deal. But, 10-15% of the time you will get scammed, and you will have zero customer service. Aliexpress will promote and back the sellers. As a result, many fraudulent sellers are growing in the platform. Once the seller gets a lot of bad review, they start listing with a different name and continue to scam people. So, if you get a good deal, you might be lucky to it to be legit. I would prefer Amazon or eBay over Aliexpress, even the price of the product is twice than Aliexpress. I would only shop at Aliexpress, if the product is not available at Amazon or eBay. Fortunately, Amazon is growing their inventory very rapidly, at the same time giving more and more competitive price. In 10 years time I foresee, Amazon will take the whole market share of Aliexpress. That's why, I am an Amazon stock owner, but, too scared to invest on Aliexpress stock.
