I'm in the market for this exact specs but not sure the return is worth the risk of ordering from any AliExpress related vendor, based on these comments.

Anyone have confidence in AliExpress?

If so, why?

I am currently dealing with EcoWorthy through AliExpress, and this has been, without question, the worst customer service experience I have had in over 50 years. What should have been a simple return has turned into an ongoing, frustrating ordeal. The batteries I purchased do not fit, yet after over a month, I am still being given the runaround with no resolution in sight. The level of inefficiency, lack of accountability, and overall disregard for the customer is frankly unacceptable. Based on this experience, I strongly caution anyone considering a purchase to think twice. I would not consider buying from this seller again under any circumstances.
