I don't have this particular model but I'm a satisfied owner of this brand's gadgets. Back in 2015, I bought their tablet, the Mi Pad at around $220 I think, because it's been years and I forgot already but I'm sure it's around that price. It's a 7.9-inch IPS, NVIDIA Tegra K1 2.2GHz, 2GB RAM, 16GB Memory, 6520mAh battery, and OTG capable. It is still in great condition, no major issues yet, battery is still great and can still last for a whole day of games or videos without charging. The only downside I can take note of is its camera though the picture quality is still good enough. It has very minimal lags but only for graphics-hungry games and I think it's a common issue with all gadgets.
And because I'm satisfied with Xiaomi, I bought my next phone last December, the Redmi 4x (not Redmi Note), and I can say that it did not disappoint and actually exceeded my expectations. It has 4100mAh and it can really last for more than a day even with continuous use though I haven't used it with games yet, just YouTube and browsing. Picture quality is great and screen is crisp and clear. It has great features like screen recorder, split screen (you can view two screens at the same time), you can use it as a remote control, fast Wi-Fi, a second space (it's like having two phones, if you want to hide some apps or pictures or videos, you can put it here, though I haven't used it yet, I just put security codes to the apps that I want to keep private), in messaging you can schedule when you would like the text to be sent. I really love this phone and have no issues encountered yet, though I should have bought the 32GB variant for more storage, but it's OTG capable so I just transfer/view files to/from my USB device. I bought it on sale at $100 and I could say it's really worth every penny.
