Support is a worry
I have a Moto Z and a Moto Z2 Play, not a Z2 Force, so can't comment on that phone, however I do like both of the phones I have, and don't intend changing for a while.
I got a fabulous deal on the Moto Z with the JBL speaker mod (which is superb). I've now got three styleshells and a wireless charging styleshell, and the recent Motorola battery pack too. All are excellent.
When the battery started to fail on the Z after just 6 months (really really poor) I sent it to Motorola for repair. It took several such returns for them to fix it, and in the intervening months they'd agreed to replace the Z with the Z2 Play, but in the event sent both the repaired Z and the new Z2 to me. I have done well out of this, but it highlighted that sometimes Motorola will use poor components (batteries in this case), and they'll sometimes struggle to repair when requested. The fact that they left me with a better Z than i had at the outset (according to the Accubattery app its capacity is consistently 200mah higher than spec), and a Z2 Play has been fantastic, but for a while i used a cheap BQ that I bought on a warehouse deal, and it made me realise that the cheap end of the android market has really caught up.
My experience with Motorola must have made them a financial loss, and I can't see how they can continue for long making and selling phones against the high end brand loyalty of Apple, and the low-end value of the Chinese manufactured EU marketed likes of BQ and Nokia unless they can consistently deliver the kit and the support that keeps customers coming back again and again. They are to be congratulated for trying to do something different, and maybe encouraged to keep it going, however, I wonder whether the cracks are showing in their infrastructure if not on the Z2 Force's screen.
