@babgozd - Yes, they work just fine and last just as long as any other. The only reason people have issues is first they are usually not familiar with using, so learning curve, and then poor connection due to learning curve on getting chip clamped with the SOIC8 test clip clamp perfectly too.

Yes, some chips may not work with CH341A, but same applies to other programmers as well, not everything is going to be compatible with everything. Be sure to pickup a 1.8V adapter if you think you may work with 1.8v chips
