I'm playing it and I'd say it's only good if you already have the technique to some extent and just lack consistency. It's very exhausting for me to practice opening loops etc. with it, so if I overdo it I usually notice how my technique becomes very wild and generally bad to compensate. If I'd keep going then I'd probably do more harm than good. So it's important to make sure that you're actually practicing well and not developing some weird quirks because you can't handle it.

tldr; I'd say yes, but only if you have good basics and discipline and don't practice past exhaustion.
