The delivery was fast and the price is affordable. The use as a Bluetooth speaker is a bit lacking, but it's convenient to connect to a guitar and use it easily. It's very lightweight. The box arrived all crushed. I'm not sure about its durability, but it's nice to use on a desk.
Very nice to practice with it, it’s own drive is pretty cool
It's just audible, nothing more.
I really liked the product! I already have a mini amplifier from another brand, and I'll keep this one for transport. For the price paid, I think it's a great value for money. It has a good sound, both clean and with distortion for what it costs, and it even serves as a decoration haha... It was worth it!
Incredible! It's really worth it, compact, good design and sound.
Nice! The model i received has the telec certification number. However, it seems that all audio output is monaural.
Its size is a bit small, but the sound is excellent.
Good!!
Good product for a beginner guitarist's basics
Small and easy to carry around. i'm happy with it.

The Joyo mini amp is sensational! Excellent for studies and rehearsals with small, intimate groups. Despite being small, the Joyo mini has a volume that's not embarrassing and a gain that gives a boost even when the overdrive is not turned on! I really liked it! I'm extremely satisfied!

These mini amplifiers are excellent! They are worth every penny! You can buy with confidence.
Product delivered as advertised and working perfectly. For those who need a compact amplifier for studying at home, it offers great value for money. Its clean sound is a bit lower, but the distortion is more defined. It's quite comprehensive and meets its purpose. I really liked the product. I recommend it.
I was quite surprised by the clean sound it offers, and the Ovedrive is very good for being so small. If you want an amplifier for playing at home or taking it wherever you want, this one is perfect 💯
The sound is much quieter than I expected.
It's cheap and looks like a toy, but the sound quality is clear and it's perfect for using in a corner of the house. The Bluetooth works well too. Mini amplifier with many functions, spark and pulse mini display Or, buy this instead. I bought it for 26,000 won using a coupon and I'm satisfied. It's small for an amplifier, has no extra features, uses rechargeable batteries instead of batteries, and is just perfect.
Great product, exactly as described. very happy with my purchase!
Good quality. acceptable for practicing.
very nice
Considering the sound quality it was going to offer, after much comparison I decided to buy it on sale for €17. I am totally impressed by the clean sound it produces with a medium tone and full gain; it's capable of saturating, not comparable to a tube amp but it holds its own. When you activate the gain, it's a rock distortion, I like it, but I mainly use the clean channel. If you're looking for a gadget like this, the quality-to-price ratio is better than any other in this price range.
Pretty good, not that high, but that's the goal. It's very natural and of high quality, even the drive surprised me. If it had a reverb and a delay, it would be perfect.
Very good speaker, easy to use. I cared that its aux input had no latency so I could connect a pocket master and play guitar that way. It met my expectations!
