Title: Poor Customer Support and Firmware issues

I recently purchased a TENNIIX ball machine, but I have encountered a firmware update issue that I have been unable to resolve. The machine connects to the app but I can’t use it.

Even more frustrating, I cannot select any drills in the app. This completely undermines one of the machine’s main selling points. The ability to use different drills and structured training routines is one of the main reasons to purchase this machine, and without this functionality, its biggest advantage is essentially reduced to zero.

I have tried troubleshooting these issues myself and contacted customer support for assistance, but I have received no response. It is extremely frustrating to invest in this product and then be left without proper technical support when something goes wrong.

Update: Customer service sent me an email with instructions to update my TENNIIX firmware with a previous version of the app and that solved the whole problem and started working very well.

Got better - but some issues persist

Recent updates improved things. However, “AI”challenge mode assigns points in match mode but “send balls out of bounds” when using top spin. In pro game I counted 12 balls that landed out of bounds (30%). “Ai” is truly overused.

神アプデ

画面が見やすくなりわかりやすいです。さらに手をかざしたら射出が止まるなどアプデが神でした。そんなことまでできるなんて。

Better 2.0 app but still doesn’t work

At least the app can now find and connect to my Tenniix machine, which is an improvement. Unfortunately, that’s about as far as it goes. The app still won’t check or update the firmware, I can’t use any of the drills, and I’m unable to properly control the machine through the app.

The customer support experience has been just as disappointing. Every time I reached out, I was repeatedly asked to send videos of the problem instead of being given an actual solution. After going back and forth and wasting months trying to get this resolved, I eventually gave up.

For a machine that relies so heavily on the app for its features, this is extremely frustrating. The hardware may have potential, but the app and support seriously need improvement.
