Coming from Nokia 3210, Moto Razr V3x, Nokia E61, Samsung P780, HTC HD2, iPhone 4, Lenovo S890, Lenovo P780, Alcatel Idol X, LeMoto K910 and previously Huawei Honor 3C.
Got the ZTE Nubia Z7 Max unit from Lazada with RM150 discount at RM1,149. Playing for 24-hour already... It's rooted 4.4.2 KitKat under NX505J_CNCommon_V1.32 ROM. Here's my comments about this unit:
A = Android = NubiaUI 2.0 KitKat is acceptable. Lots of junk apps out of the box. After rooted, can be frozen/uninstalled.
B = Body-Built = ZTE managed to make the plastic feel 'acceptable'. Buttons are nicely placed and decent feedback. Capacitive buttons with interchangable functions (menu vs back) are a welcome feature. Thickness and weight are comfortable. 3rd party casing and screen protectors is encouraged but I leave my unit naked.
C = Call quality = Second place after my previous Moto RAZR V3x. You can get reception even inside elevator or basement one.
D = Data = LTE modules for both micro-SIM 1 & 2 are the best out of all phones I've own. Previously the record was held by Huawei Honor 3C. Bluetooth is stable too.
E = Email = Email client is flexible compared to other Android-based phones. It works as intended.
F = Free-apps = None which is shame. I was hoping lifetime WhatsApp license just like the Alcatel Idol X.
G = Games = As expected, heavy titles are not an issue with Snapdragon 801 and Andreno 330.
H = Hangouts = Video call for Skype, Google Hangouts, Tango etc. is superb for 5MP front facing camera.
I = Internet = AOSP browser is smooth. No checker-board effect on heavy websites.
J = Juice = 3100mAh = "Decent". Claimed talk-time, stand-by time, etc. are achievable for dual-standby-micro-SIM LTE phone. Power consumption during idle state is 2% from 11pm to 5am. Daily usage can threaten my previous LeMoto P780.
K = Kamasutra

= Phone vibrates with notification/ringtone. Vibrating sensation is above average. Ladies may use it for other purpose(s)... LOL...
L = Loudspeaker = The loudest out of all my previous models. DTS manipulation is pushing the loudspeaker further. But crack if treble is too high. Bass is above average.
M = Music = Again the DTS technology does its magic. Headphone/earphone usage is encouraged.
N = Navigation = Working as expected. Lock satellite within 10 seconds. Waze and Google Maps are working normally, even indoors.
O = One-hand Operation = I have "big" hands and "long" fingers ;-) No further comment.
P = Picture = 13MP is exceptional packed with standard camera features/modes. Dept-of-Field feature withadjustable lighting condition is one of its kind.
Q = Quirks = tap-hold to bring cut-copy-paste-select does not aligned properly and difficult to tap. But this can be improved in their next ROM release.
R = Rooting = Super-duper-hyper EASYYYYYYYYY. TowelRoot is the one-click rooting tool. Mod ROM is also available but not purely ROW ROM.
S = Sound = Earphone sound is OK. Speaker-phone is OK too but crack if too loud. The DTS manipulates the sound brilliantly.
T = Texting = Stock android keyboard should be replaced with Google keyboard.
U = User-Interface = smooth & flexible with various themes to choose. Thanks to the 2GB RAM.
V = Video = Capturing 1080P video is acceptable. 4K is limited to 4 minutes due to overheating. Auto-focus is acceptable.
W = WiFi = The best out of all smartphones that I have own. Previously was Huawei Honor 3C. Others only manage to get 1-2 bars in my basement floor test. But z7 Max captures 5 full bars without fail. Honor 3C gets 4 bars.
X = X-factors = For dual-micro-SIM LTE phone with 2GB RAM supported by 32GB onboard storage is worth every penny. Strong voice/data/Wi-Fi reception is a desperate move for those who live in the outskirts or camping sites. Gamers will like this unit too.
Y = YouTube = The 5.5" IPS screen accompanied by excellent LTE connection is surely an enjoyable experience.
Z = Zero-figure. Imported from People Republic of China (PRC) unit at Malaysia Ringgit RM1,149-point-zero-zero is a smart investment with high internal specs.
CONCLUSION : Buy it if you are looking for high-spec phone having dual-micro-SIM LTE support. Gonna clinging to this unit until Huawei Ascent Mate 7 is available in local market.
