Does exactly what it says for $30! No more no less.
I just got it an hour ago, and right out of the box I plugged it into my Ibanez 6 string. and it works beautifully. The sound is wonderful (For what it is) If you compare this to a more expensive amp you are cheating yourself out of a good product, because you will think it is not as good. For $30 this is a great travel/practice amp. You can get great clean/overdrive/crunchy tone out of it. It connects with my phone and I was able to play some backing tracks on Spotify from my phone to jam to. I personally love it! Will it replace my main amp? NO! But it is not supposed to, this can be bought for pennies and works straight out of the box with no setup. This is great for your 8 year old's first practice amp. Even at full volume, while the sound was clear and nice to me, my wife was able to watch television in the next room, without problem. You can use it while charging, so during long jam/practice sessions, when the battery eventually dies. You can just plug it in and continue playing. I have not had it long enough to comment on the battery life, but every other aspect of it I love so far, and I give it that 5 star rating honestly. My two criticisms are small ones. First of all, it rolls around in the output port of the guitar, as you move or shift its weight, it does not stay still. I worry about breaking it on something as it sticks out from the guitar very far. But even still it is only $30 to replace it if it does. It would be nice to have a mounting bracket (Sell it separately to not increase the price of the unit) But a simple 3d printed bracket to clip it to the body of the guitar better would be something I would buy. The additional 6.5mm adapter that came with it makes no sense, and I am not sure what it is for, and it is not mentioned in the owners manual at all. I thought it would attach to give some more space between the unit and the guitar if you wanted that. But it does not. The unit also comes with Bluetooth functionality, very cool as I said you can plug it into the guitar, connect it to your phone, and then play music or a backing track from your phone to play guitar along to. Or if you just want a small portable speaker to play music from your phone with, it will do that. The owners manual, shows you just propping the amp up on the connection adapter, like a kick-stand. However Guitar people will not want to do that as it can damage that adapter and cause an unwanted buzz or other unwanted sounds. So you could 3d print a small plastic cover to clip onto it, so when you use it as a kick-stand the metal of the adapter is protected from scratches. Do those things and I would give it 10 stars. I would buy three or four more of them to keep in various places like my gig bag, or my friends house where I jam and practice a lot. This is a good product, that is worth the 5 stars and the $30 already. Those two additions would make it way better.

Great little amp
The tiniest amp and it works great! My son built an electric guitar 🎸 in wood shop so I knew an amp was in our future. I wasn’t sure if this would be a passing fad so I wasn’t about to spend a lot on a standard amp. This works well, obviously it’s easily portable. He will use it several times before I pull it off his guitar and charge it, so probably 3-4 hours of use which is pretty good battery life. I know that he plays around with the controls but in general I can’t give an opinion on the different options or on the sound quality like some audiophiles might. It sounds good to me, my son is getting better and I can tell when he’s hit a wrong note on an old Metallica song. This is a great starting amp for someone just learning. My son will sit outside on the patio and practice, brought it to school to play with friends, took it camping… it’s portability and ease of use is a bonus, and the price was right.

About what you'd expect for $24
This is a good option if you live in a place where space and loudness are limited. The sound is good for what it is. I wouldn't recommend using with electric acoustic guitar because it will be hard to hear. On electric acoustic It will sound exactly the same as your acoustic guitar, so you may not notice its even there. With electric guitar, it makes a difference. Greater depths of sound. However, the range of sound will be very limited compared to a real amp. It will not pick up the sound of all the guitar knobs. It provides convenience. I wouldnt recommend using for performing. A $100-$200 amp will sound much better. Or get spark headphones. Its worth having. With this amp I can get about 2 different distinct sounds. With my headphones i can get 1000s of different sounds. This is just good for its size and accessibility.

Suprinsgly awesome!
This thing is a lot of fun! Boosts volume just enough for some nice tones on acoustic. Surprising crunchy distortion. Bluetooth a song to the mini amp and play along with it too. For the price, I am impressed! And will travel with it. 5 stars. :)

It's ok, but a few odd decisions
For $24, you can't expect too much. The sound works, It's portable, and has a rechargeable battery. The sound is ok. It lacks low end and distorts easily when overdriven, but again, it's $24. The clean+reverb and overdrive+reverb really aren't bad, but the distortion setting is ugly. The reverb really helps out the first two sounds. But does this work for noodling around on the couch with out dealing with wires, or maybe even playing along with another quiet instrument like a digital piano? Yes, and it's worth it. However, there are real issues if you're fine with a lackluster sound. Something unavoidable is if you turn the speaker towards you, it's then playing straight into the pickups. This causes tons of feedback on the distortion setting and makes it near unplayable. If you're a metal head wanting to dirty tones, this isn't for you. The other issues are just poor design decisions that wouldn't impact price. First, as another reviewer pointed out, the fit in a strat style guitar is bad. I have a G&L Comanche with a strat like body, and the plug just barely fits in the front facing jack on the guitar. They could have extended the jack just a few mm and it would have been so much better. I took away a star for that My biggest issue is that when the amp is turned on and NOT connected to blutooth, the blue LED blinks. Why??? It's so annoying. I'm trying to play and there's this small blinking light in the corner of my eye. It's distracting and such a stupid design. The blinking supposedly stops if you connect it to a blutooth device, but I don't want to do that. I just want to plug it into the guitar and play and not have to connect anything else, but now there's a blinking light. Can they update the firmware with this somehow??? I was about to send it back but then I covered the LED with electrical tape. It's mostly hidden the blinking, but I know it's there. Ultimately I'll keep this thing because it's cheap and I'll actually use it. It even sounds pretty good with my Fender Acoustasonic! Yes, a $24 amp plug sounds good with a $2000 guitar. But why does the LED need to blink at all??? just change the color when connected to blutooth instead.

works good for me
shipped super fast, seems to be of good quality, some said it wasn't very loud, but it is loud enough for my taste. it takes the worry out of having to constantly mind the cord...gives more freedom. i like the fact that it is usb rechargeable and seems to have reasonably long life between recharges. all in all I like it

Great little travel/ practice amp!
This is a fantastic little travel/ practice amp! This tiny amp fits in my guitar case and plugs directly into my guitars. It has three nice tones; clean, overdrive and distortion. All of them sound pretty good, considering the size of the amp and its plenty loud. It also uses a USB to recharge the amp. Its a great little amp to keep in your guitar case, especially if you travel a lot, but still like to play.

Struggles to stay plugged in (But works perfectly otherwise)
Bought this as a gift for my friend, and he liked it. It's a bit hard to keep it plugged in, and since it's a little heavy, it tends to slip out of place. However, the quality overall is really nice. It has several settings, and the tone adjuster works well. I bought it for my friend as a practice tool. It’s small, portable, and looks decent. It's an easy way to play without an amp. My biggest concern is that it struggles to stay plugged in with certain guitars/instruments. Also, it works on other instrument, not just guitars. Worked on my bass, Q-Chord, and others
