I always offer them to take a demo model and run a long thread.
After 2-3 weeks use I return it or buy it.
I really wish they would send you one to test out. Did you already contact them and did they reply or just straight up ignore you?
The emails are above.
To repeat less then a day of email contact and they opened presales two weeks early.
Read those emails and draw your own conclusion as to why they opened preorders early.
Also draw your own conclusion as to why they told me pay for the demo up front.
