Regarding after-sales, product quality is good. But for high-rise apts without elevators, like school dorms, I don't re***mend buying. JD delivery doesn't reach upstairs. Before moving, unpack to check. Else, you might get damaged items due to poor packaging. After damage, seller only offered refund, no replacement. Had to return it myself. Also, ***pensation in JD beans was disappointing. Despite this, I'll still give them an extra star.
