I'd probably give 3 stars for the app which is let down by excessive notifications. 2 stars for delivery speed but 1 star only for customer support when things go wrong. Unable to get recompense or help after being supplied a product with missing parts. Waste of time and money - better I'd bought from UK. Won't bother with AliExpress anymore. I guess 'Buy Cheap get Cheap' is the rule of thumb here.
