Very easy to use on first day without reading the manual, which is very short anyway. Joysticks are a very convenient way to add complex LFOs that you can record (up to 8s for this product). Note that the joystick has a softer resistance than the Planar from Intellijel, which makes it unable to keep its position if you use it vertically.
Some modules from first batches, including mine, are affected by a small labeling issue: there are two "Ch.3" printed instead of a proper Ch.4. Also, the back of the module shows some exposed cables, which gives a not so good impression on durability or build quality.
Overall, i recommend the module for its simplicity as a quad channel gesture recorder, but i think the overall build quality could be improved.
