It is very easy to use, I do not have any problems with it at all! There are no downsides that i can see so far! If you want an excellent way of cleaning up your sound without having too many plugins or spending too much money then this plugin will be perfect for you!! You should definitely try using it if you haven't already because there really aren’t any cons about it yet in my experience as long as you follow their instructions correctly everything works perfectly fine no matter what type of file format you put into them (wav/mp3).
They also offer some great tutorials online which help make things easier when first starting out but they don’t go over how exactly certain functions work like EQ filters etc. Hope this helps anyone who needs to remove background noise from recordings especially vocals. This has helped me get rid of those unwanted noises making sure that everyone hears clearly again! And now people cannot tell where one person ends and another begins while listening through.
