Great Oscilloscope to have under small budget

The best handheld oscilloscope to have under small budget.Using this Oscilloscope for a few months now and it works good and perfectly measures waveforms. It has a good bandwidth allowing us to measure RF signals too.There is no fear in measuring mains voltages because it is handheld and has no ground connection.Downsides:1. Function generator is tricky to use.2. Supports only one probe.3. Trigger mechanism is tricky to use.4. Non customisable voltage multiplication factor.But overall this Oscilloscope is best for hobbyists and engineers who are looking for an Oscilloscope in small budget.
