Mine was shipped through DHL. Despite previous bad experiences the frame shipped pretty fast... Until it got to the USPS in the US where it spent a week in customs.
The motor that came with my frame wasn't the correct one. After contacting and sending them pictures, they realized they sent the wrong motor (Vortex instead of Typhoon version). As of this post, it's been 9 days and they still haven't shipped the correct motor. I suspect they ordered / QS sent the wrong batch of motors. They say it should be shipped in a few days due to being in the wrong stockroom... I'll believe it when it happens.
On the other hand...
My old broken e-bike that I don't ride anymore still has a working "750 watt" rear hub. Turns out it has 10x130mm dropouts, so it should fit in the frame. When I tried to get the motor in, it was not just a tight fit. It was not a Tight fit. It was a TIGHT fit that required a bunch of banging with a rubber mallet to get the axle all the way into the dropout. Probably due to the paint inside the dropouts but I won't have to worry about the axle spinning through a full inch of TIGHT hardened steel
I guess that's a good thing though. Even though it's not the QS-powered rocket ship, it will be rideable and quite a fun mountain bike once I get the load-cell based PAS working.
Find weakest component, upgrade it, repeat until satisfied. Rome was not built in a day.
When in doubt, get bigger MOSFETs / Batteries / Motors / Etc.
