### 3/5 — 最高

*2025-04-23, version 4.9.3*

思ってたよりモッチーでした

### 1/5 — iPad Air 5 doesn’t work with fifish app

*2024-07-02*

My iPad Air 5 does not work with the fifish app. Please fix.

### 1/5 — Unreliable, chaotic, waste of money

*2024-06-07*

I am an ocean engineer and had purchased the FIFISH to assist in U/W video inspections.  The unit displays chaotic thruster operation, making it unusable.  Customer support is non existent and the unit has failed to operate properly from day 1.  An utter waste of more than $5,000!

### 1/5 — Terrible app for a terribly expensive product

*2024-03-29*

I have been troubleshooting my drone for two weeks now. The Wi-Fi router on the remote controller seems to work, but the onboard ethernet of the drone connects and disconnects to the over and over again. Customer support is located in China so trying to get a response is untimely. Another user mentioned their drone does not always recognize the camera. It also fails to see that there is on board storage installed via an SD card. I have the same issue. The drone first worked when I got it two years ago. Very unhappy customer.

### 1/5 — Terrible App! Needs a LOT of work!

*2024-02-15, version 4.7.7*

App crashes, half of the features do not work correctly on iPhone!
Support for the Fifish is TERRIBLE!!!!
I bought a V6 Expert with grabber… only turned it on Once (never even seen the water) had a few issues so tried to contact support & don’t seem to get any sensible help!

Terrible ROV!
