Many of these cheaper CN-ones also comes packed with other features, outputs with dedicated sockets/screw terminals at the top & bottom...
like freq counter, freq generator, 10bit PWM control, signal out & and all that jazz, though if it's to any use in practice, likely varies from person to person.
Got this one from the UK a handfull of years back (Banggoods UK store)., was around 10 euro with an acrylic case delivered to DK.

If its a good component tester, I dont know. havent compared it to others, - I do like the fact that it constantly updates values 0n the screen when adjusting pods etc, or checking components, but check Youtube for reviews to gain an overview of which model does what - and how well, as there are so many models of these "CN component testers" that you literally could feed pigs with them.
a minor con on some of them is the lack of an inbuilt battery, though an easy fix.
