Want to get a second-hand psv, is it reliable to go to Haoyue Island on Taobao?

I heard that the customer service response of Hao Yuedao is very slow.

However, judging from the comments on Post Bar and Taobao, there are very few people on Black Moon Island. I once saw that there was something wrong with the PSV bought by Hao Yuedao Post Bar, and it was returned after exposure. The poster may think that he deliberately delayed because his reply was slow, but the owner of Hao Yuedao explained that his reply was slow because of some temporary things.

I think it is more expensive for you to buy a new one. Now the PSV3.60 machine is not too expensive, but the memory card is expensive.
