I bought this to replace my iRig setup which was a total pain to use.
It still required me to use an instrument cable so I always needed somewhere to have it laying on.
It was still more portable than an amp, obviously, but it wasn't practical. It also only works with an app that's not that well made, doesn't sound good, and makes my phone heat up like crazy.
This little amp is an absolute miracle compared to it! I can literally walk around anywhere while playing.
In terms of features, it's got all you need! And for what it is, sounds really good.
My only complaint is the built quality. For 50€ I wouldn't expect it to feel so plasticky, but I guess that keeps it light weight.
I really recommend it though, if you travel sometimes or like to take your bass on vacation with you. You won't regret it.
