Do NOT buy from AliExpress! I ordered two replacement batteries for my JBL speakers from AliExpress. While the batteries themselves were correct, the plugs were not. The original plug is 1.5 cm wide, but the replacements I received have a 1 cm plug, making it physically impossible to connect them to the speaker. The port on the circuit board is fixed, so any mismatch renders the battery unusable. I contacted the seller with detailed photos and videos explaining the issue. After several days, the seller acknowledged their mistake but only offered a 50% refund or suggested that I disassemble the battery and solder on a new plug myself. This is unacceptable! I reported the issue to AliExpress, providing ample evidence, including photos with measurements and a video. Despite this, AliExpress stated that my proof was insufficient for a refund. My initial report vanished without feedback. I submitted another report (ID: 1143802794882327) but still received no response. It has now been over a week since my first report, and AliExpress has shown no interest in resolving the issue. They appear to be looking for reasons not to issue a refund. Additionally, shipping practices on AliExpress are problematic. They charge excessive shipping fees and don’t allow combined shipping for multiple items from the same seller, yet often ship them together in one parcel. This is poor practice and reflects badly on their business model. I have lost all faith in AliExpress and will NEVER purchase from them again. For a better experience, consider shopping on sites like Temu instead.
