Have't bought any white from anyone else yet.

Hell, still haven't tried the silver (actually grey - not at all what I was expecting) or black yet.

IT;'s such a pain to change filament I tend to just run the roll down.
It reverses the filament for a few cms and then just stops - the motor is still making running noises, but I have to pull the filament out with pliers.

I've had the extruder apart and I can't see why it needs so much force to remove it. Even with the springy tension lever open the filament does not just pull out without massive force.

That said - it feeds it in no problem and works great once loaded - it's just I'm concerned about how hard I Have to pullt it to remove it - don't want to break anything.
I change filament on the hour.

The Number 1 Rule...

When changing filament, LOAD for a few seconds and then UNLOAD.

It is trying to retract the filament that is causing you headaches. Inside that tube is is not 1.75mm, it's a bit bigger generally and it expands to fill the hole, not enough to lose pressure but wider than the original diameter. Feeding flushes this, and then you can unfeed and it comes right out - never ever jam again. As long as you push the spring you are OK.
