I have the 2019/2020 Boxer in 10 m² and it is the best kite for foiling I´ve ever had. Super easy handling, almost impossible to drop it even if you do the most stupid mistakes. And it has a super-smooth power delivery which makes foiling (particularly as a beginner) very relaxed. It has excellent depower, which surprised me first (I had other 1-strut kites before and they all had very poor depower compared to 3-strut models).
The 10 m² Boxer is very nice with strapless surfboard as well. Not quite as good as a Reo, but as a crossover kite for foil and wave it is really perfect. It is not super-fast turning, but still at least same speed as a 10 m² Reo, I´d guess. And it reacts very sensitively to bar input, with very moderate bar pressure overall. A real joy to fly.
I´ve recently purchased the 8 m² boxer as well as it is so cheap right now that the new successor model is out. But I wasn´t able to test it yet.
I´m 75 kg btw. My smaller kites are 6 m² Religion and 4.5 m² Drifter. I´m not good enough to foil when the wind is strong, so only surfboard from 20 kts and beyond.
According to https://www.gleiten.tv
the new Boxer model is identical with the predecessor, only difference is the new inflation valve (and colors).
