Adio Air GT : Solid, versatile practice amp

Overall Im happy with the amp after many months usage. Anyone looking for a practice amp and know the drawbacks and advantage of them compared to a big tube amp will not be disappointed, however given my cons below im left wondering do the competitors have the same issues or did I choose poorly.

Pros:

1.Easy to get good sounds

2.Sounds good for tiny speaker

3.Versatile as bluetooth speaker

Cons:

1.Would really have been great if rechargeable, I use separate rechargeable batteries and never bother with the ac adaptor

2.I used the app to make new sounds once, its kinda trash, very dated looking. Disappointing to buy a new product but then the app is from 2005

3. The bluetooth range is very spotty when playing songs from my phone. If the phone is 6-10 feet away it starts having issues streaming; sort of defeats the purpose of using it as a bluetooth speaker
