I agree it would be more honest to explicitly say in the product brief "this product comes with beta software which is only infrequently updated but has many known issues".
Customers can still decide if they want to get it. Loyal MikroTik customers probably would, but new customers could be put off by the experience and never buy MikroTik again. Not good.
They always writed it.....
Operating System RouterOS (v7 only)
Is a very clear advise.
That may be clear advise to the loyal MikroTik customer who has several other MikroTik devices.
For the new buyer that is as clear as mud. When you buy a new router will you check that the firmware version it runs is in fact only a beta version?
You will notice that only when you encounter some issue and try looking for an upgrade, and find out that it says "beta" in the version.
The product page does not even say Operating System RouterOS (v7beta only)
