I advise everyone not to buy the Explorer brand. I bought it last year and it was like this the first time I used it. I am not dissing this brand. The quality is rubbish and the customer service is even rubbish. Although 100 yuan is a small amount of money. But 100 for one use is too expensive. By the way, take a screenshot as proof!

Also add the store name: Tmall Explorer Flagship Store
