Sure, provided it's not faulty or otherwise unusable.
You're moving the goal posts here. This isn't the scenario you originally outlined. You oultlined a situation where you're unable to decide between 2-3 choices.
I've never found myself in this situation, I do my research, I narrow it down to the item I want. I buy the item. With rare exception (above KVM switch which had a massive functionality issue) I keep the item.
As I use it maybe I'll discover things I dislike. Maybe I'll read about competitors new offerings. I add this to my "knowledge" and use this
when buying my next model. Maybe the severity of these accelerates the timeline by which I upgrade and sell the old one as used but that's about it.
Hantek performance fully matches the stated specifications.
Have you read the threads concerning these? They mostly just don't work. It is an implied (so much so it does not need to be mentioned) specification of ANY product that it works.
Then you would not buy that brand period.
