I doubt two thing with this new printer.
First that it was developed with the goal of being as reliable and lasting as possible.
Secondly that ALL machines will reach their users free of defects and/or loose things that might cause issues at a later stage.
That however does not mean it is a bad machine because there is always a few lemons out there - no matter the manufacturer.
I had a dual head printer before and in hindsight going with a P1S combo to replace it was a step back, not forward.
Well, not in terms of print speed and some other factors but this single head is far from ideal.
The H2S seemed like a logical step forward, so why I did I not jump onto the pre-order offer I got from Bambu ?
New toys often comes with kinks, flaws and issues.
Most are fixable and if not you get the new parts required under warranty.
But from what I have seen so far this new printer is not as advanced and high end as I expected it to be for a flagship model.
Yes, it is a great design, one trying to keep things as compact as possible…
But it is also ‘just’ a lightbulb thing for me - like with Edison who did not invent the lightbulb.
Still a core-x machine, still using more than common mechanical drive solutions, still just a dual head system with build in limitations and restrictions caused by or based on the design decisions made.
A fantastic machine for most but for me still quite far from I would expect from a dual head printer.
Don’t take my expectations as a requirement though as I not the average user 
Many people spend a lot of money on things they don’t really need, like drones, a second car for the weekends to impress the other sex, collectibles,…
A printer is still just a machine and one the owner has to have use for to justify having it.
But I see more and more people who jump directly into the deep end of the pool because they have the money to spare and no financial worries on the horizon.
“I’m new here and just sorted with my first printer and have a few questions…” - saw posts like this more times than I count but these days their first printer is often top of the line…
What came first here, our ‘need to print things’ or machines and software combos claiming that even a total noob can get outstanding prints right out of the box
Impulse buying …
Bumbu has a working support and warranty system, not always the fastest to react but still better than some other companies I have to deal with.
Compared to the market their prices are not bad either, still to highly priced but that is normal since the pandemic.
The decision should not be based on whether you are worried or not, just based on on whether YOU think the price is acceptable.
And well you should be aware of the Bambu policies for security and privacy…
There is plenty of other options out there and there will always be new models coming…
Choice is yours.
