The best value scope in it's category, 4 Channel entry level. I wouldn't say it competes with the Rigol because this one is already preloaded with all the decoding features and doesn't need to be hacked for full bandwidth.
One note, you can't upgrade the bandwidth, not that you would want that for a scope like this, 100MHz is plenty for field usage, debugging microcontrollers, power supplies and audio circuits. And the 4 channels is way more important for more complex measurements.
The only bug I've found is related to triggering, in some rare cases stopping will show multiple trigger results at the same time without persistence being turned on, changing the timebase fixes it.
