Has anyone purchased a phone from TechCrazy lately (previously known as Challenge Mobiles)?

I'm looking to buy a Samsung Galaxy A8, and TechCrazy have a dual SIM version (presumably imported version), that looks good (dual sim version a bonus, for when I travel to AU for work).
To replace my current Galaxy A3 2017.

There doesn't appear to be many smaller phones these days (e.g. 5.5" or less), and the A8 only seems like a slight size increase from my current small A3 (4.7"), and fits my requirements (not too big, IP68, works on Spark's 4g 700mhz and 1800mhz, bonus of ANT+, and FM)

Maybe I'm just the small minority who want a smaller screen, where as the majority like 6"+ devices in their pocket.

However there don't appear to many A8's left at normal retailers, hence looking at TechCrazy.

Thanks in advance.
