Bought a few aluminum and metal case and tried them...
Within a minute, I threw them away and use back my simple and humble 0.3mm TPU transparent case.
Those simi aluminum and metal, hard shell case just make my Mi Max so bulky to hold in hand and looks ugly. So freaking regret buying them and wasting my hard earned pocket money from my parents!
I know, tpu case turns yellowish. But hey, at that cheap price of just $2.00 per tpu case from online store, I could buy 10 tpu case and keep changing to the next brand new tpu case as and when I feel that the current one has turned too yellowish to my liking and it costs just $20.00 in total...
What can I say and ask for more!
