This small plastic box offers many, many things in a very contained price.
But I warn you, it doesn't sound like a real amp and as a multi-effects it can't keep up with any other in the market, even those half the price of this device.
I'm not returning it, because I knew more or less what I was purchasing, but I must say that the YouTube reviews of this device that I watched before purchasing it are mostly delusional.
To put it in just a few words: This is not a quality sounding device, but just a (very) practical tool to use everyday or when you travel.
The sounds are just OK, the overdrive/distorsion effect is not tweakable and neither is the built in noise gate, that cuts the sound earlier than you'd like.
And as the basic DSP is all but powerful, some effects worsen the latency to the point that it's just too much. If you keep the focus on moderation (low levels, no simultaneous effects), it doesn't get ridiculous.
On the other hand, the tuner works quite well, the looper fulfills its (limited) role, the few effects are basic but functional and the speakers can't stand too much volume, but are surprisingly decent for an indoor quiet practice.
The drum machine would be nicer if they had created more usable rhythms and less 'experimental' ones. I just can't understand why they do this. Also the sound feels quite limited. Don't expect real sounds here.
But again, the device is designed to be the easiest tool for practice and thus the layout is straightforward and its functions are extremely easy to work out. If I hadn't previously read the manual (I'm one of those rare individuals that does it) I would've had no problem at all to find out how to get to every functionality and sound.
All in all, I'm not disappointed, but neither I am excited.
I wanted exactly this specific product (there's no one out there like it currently) and it's exactly what I got, nothing more.
I didn't want to spend most of my time tweaking parameters to get a decent sound and I definitely didn't want to depend on the smartphone or any other device to use this one.
This is what many people actually need and want for their free time with their guitar.
Seriously, I've had some multi-effects in the past and I still have a very good one, and I know how frustrating it is to spend half an hour just tweaking the hell out of it to finally leave the room exhausted and discouraged.
Sometimes you just have ten minutes and want to forget about screens.
And this is what this limited, imperfect, cheap, small portable device can offer.
Pros:
Ultra portable: small size, battery-powered.
Decent tuner.
Pedals (the only mini-amp that has them).
Drums: a nice detail.
Practical: you get three switchable sounds almost effortlessly.
Easy to use (except with the ridiculous, unreadable screen).
Easy to charge.
Easy to connect and record.
Cons:
The screen is a joke. It's not tiny, is microscopic. You need a magnifying glass to read some parameters.
Noticeable sound lag, latency.
A bit cheap feeling. Some encoders are wobbly.
Unsecure smartphone handler. There's no locking mecanism, the legs just insert in their holes and that's it.
Some crazy (unusable) drum patterns.
