Sunwa's YX-360TRD Multimeter is great for testing wire connectivity, detecting levels of voltage in AC or DC and current, as well as determining resistance. It is an analog multitester, which I'm more comfortable with using than the digital.
What I like most about this multi tester is because it has a lot of features and the range of values it can detect is quite good. It's very sturdy, I've been using it for at least 7 years now. I recall changing the battery only once or twice, which means it has a very low power consumption, and thus it's very cheap to use.
It's very good quality and very accurate, which will be essential for all my electronics and troubleshooting work.
I would highly recommend this product. It's high quality, durable, and the price is decent.
