Can Balloons still be useful at Town Hall 7?

I am a Town Hall 7 and I really like balloons. I don't have much Dark Elixer to fund a Balloonian army, and I was wondering if Balloons can be good at TH7. They are Level 3 upgrading to 4.

Balloons aren't that good until you get them to lvl 5. I rarely used balloons as th7. If u do use them, save up your dark elixir for balloonian. It doesn't cost that much dark. Look for people with low level or badly placed air defenses and take em out. I suggest 2 heal one rage. Good luck!
