For its price, it is truly unbelievable. Easy to use and with truly endless options. Ideal for beginners or someone who is not interested in using it live. Very good build quality despite being plastic. A big advantage is that it works with both batteries and is powered by USB. I did a live performance by connecting it to a small power bank.

First impressions
1. Plastic construction that doesn't pose a problem.
2. It runs on power supply (not included in the package), batteries (provided), and a USB cable (also not included in the package). To connect it with the Guitar Lab app (which is very good), I had to try 2-3 different chargers until I found one that worked. I don't know what the issue is.
3. The pre-installed sounds don't impress a metal guitarist and require some searching to find something good.
4. It's not particularly difficult to use for basic functions. However, if you want to explore and experiment with the sounds, it requires some familiarity.
5. I consider the price of 65€ to be good.
