### 2/5 — Many issues - not very intuitive

*2026-08-18, version 1.5.4*

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.

### 2/5 — Many issues - not very intuitive

*2026-08-12*

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.

### 1/5 — Sloppy - they never bothered to test the app or their instructions

*2026-07-28*

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.

### 4/5 — Goodish

*2026-07-16*

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

### 1/5 — ログインできない

*2026-07-12*

アカウント登録してるのに登録されていないことになっているため、ログインできない。改善求めます。

### 1/5 — Can not use features

*2026-07-08, version 1.5.1*

The app requires an account to use many of the advanced features, but the creat an account flows don’t work.

### 1/5 — パスワードリセット出来ません

*2026-07-07*

いろいろと不具合ありすぎ。。。

### 1/5 — 使えない

*2026-06-30*

不具合だらけでアカウントの登録すらできない。早急に対応してください。届いても何も使えない。

追記
1週間使っていないだけで電話番号、メールアドレスのアカウント情報が登録されていないとされ、アカウントが削除される可能性がある。バグが多すぎる。

### 5/5 — app越来越好

*2026-06-25*

现在app比之前做的好多了 清晰明了 鼓励分给到

### 1/5 — ソフトの出来が残念！

*2026-06-12*

ハードや機能面はよく出来てるが、何しろ操作性が悪い。アプリを通して設定やハードの操作を行わなければいけないが、直感的なインターフェースとはなっておらず、必要な設定に辿り着くまで手間ががかかり過ぎる。
アップデートで今後操作性や使い勝手が向上することを期待してます。
