It seem like really nice. Great stuff can be buy. The prices are a little bit high. At a moment a xiaomi red rice (hongmi) is about 220 dollars (it's special price), but in other stores it's ***** dollars. But the accessories are awsome.
Unlike some other sellers in China, Xiaomiworld stands behind its products. You may pay a few dollars more here, but I'd rather pay it and know that XiaomiWorld stands behind its products. I've purchased a few items here and had great experiences each time.
