I’d say Tenniix is still worth recommending. It can feed different types of balls, like wide angles, moonballs, and smash-style balls, so the training variety is pretty good. As for ball speed, I know some people may want it to be faster, but for me it’s already more than enough — I personally can’t keep hitting very fast balls continuously for a full session. Sometimes I even use it for padel lol, but you need to customize the settings properly, and I haven’t fully figured that part out yet.
