バグ多い

チャレンジモードの守備型以外が反応しない。攻撃型は最初反応するが1.2球出たら停止してしまう。
また守備型でもレベルの認識が選択通りにならないことあり。

Many issues - not very intuitive

Heavy on marketing but little on substance, e.g. actual documentation and use info weak. Landing calibration: “short serve” instead of “shorter serve” for clarity.

AI module assigns points in match mode happy to send balls out of bounds when using top spin.

If you are 3.5 or higher, be prepared to do a lot of trial and error to figure how to operate different features. I don’t think the marketing folks even tried to use the machine.

Check pingbot, it was not available when I got tenniix. They might put more focus on the use-performance over marketing.

Many issues - not very intuitive

Landing calibration:When selecting “short serve” as in “serve is short” the app makes it even shorter. “Higher serve” works as expected though.

After calibrating machine on baseline, the training mode pic shows machine in between serve and baseline. It’s not one of the positions recommended in the manual. AI module assigns can assign points in match mode but will happily send balls out of bounds.

Sloppy - they never bothered to test the app or their instructions

Landing calibration:When selecting “short serve” as in “serve is short” the app makes it even shorter. “Higher serve” works as expected though. The x is so small, impossible to see when the sun is bright.

After calibrating machine on baseline, the training mode pic shows machine in between serve and baseline. It’s not even one of the positions recommended in the manual. The balls fly short with the default settings. It’s my third session, Im still struggling with the thing. Also some balls fly much higher.

Goodish

Account errors, firmware errors, but once i finally got it working the app was fine and did what i expected.
