If it was you who damaged those channels, I wouldn't expect the inputs of a Chinese scope to be a rugged as those on a TEK.

I wouldn't go for the rock-bottom brands like Hantek or Owon. They're very limited.

There's no reason other Chinese brands won't last 10 or 20 years. Rigol/Siglent/GW-Instek brands are rock solid.

"failed after hours of use", "failed after days of use", "screen is corrupted on arrival", "failed just after 1 yr warrantee", and so on.  Complaints filed on many models even on EDU tek and keysight.

Yeah, that's "Amazon" users for you.

The very first thing they probably did with them was connect them to mains electricity with the probe on 1x setting just to see the pretty sine waves.

You aren't going to do that, are you?

May be 30 years?

It's cheaper than a function generator to make a test !  ;D

TomKatt:
'Made in China' isn't really a reflection of a product's quality...  Pretty much every Apple product is 'made in China' and they seem to set the bar for what consumers expect for quality.

Like anywhere else, there's well designed and manufactured gear, and there's cheap low quality merchandise.

From my limited experience, provided you steer clear from the non-name cheap rubbish and go with some kind of name brand that carries some respectability (like Rigol, Siglent etc), those products will last as long as anything else in their class.

Where any modern piece of test gear suffers is in reparability - while you can maintain an old analog scope and find repair documents and replacement parts, modern gear is simply less repairable by the average hobbyist.
