All in all, a great budget option if you want a "premium modeller". It sounds fantastic, the unit's interface is the best and the most intuitive out of all the modellers I've used (Quad Cortex, Helix, Ampero), but...

And don't get me even started on getting the software to work. There's a big chance that your browser won't even let you download the drivers, because it registers them as virus. Also, the software won't work if you download the latest edition. You have to download ALL the editions and then install them in order. Also, sometimes the updates aren't available on the English site, so you have to download them from the Chinese site.
