A small single-channel handheld scope with 200kHz bandwidth and a 2.5MS/s sampling rate. It is a learning instrument: enough to see audio signals, PWM and slow digital lines, at a price that makes the oscilloscope less intimidating.
Treat the DSO152 as a teaching tool rather than a lab instrument. Its bandwidth is far too low for microcontroller buses, but for seeing a 555 timer oscillate, checking PWM on a motor driver or watching an audio signal, it makes waveforms click in a way a multimeter never can. When you outgrow it, you will know exactly what a better scope needs to do.

Start with a known signal: many kits include a 555 timer or a PWM output, which is ideal. Set the trigger to auto, adjust the timebase until you see a few cycles, then switch to normal trigger to stabilise the trace. Keep in mind the bandwidth limit — a signal that looks rounded or smaller than expected may simply be faster than this scope can show.
Beginners and students who want to see signals for the first time without a big outlay.
Two channels, 50MHz and a built-in multimeter and signal generator — the handheld to buy if you plan to keep using it.
