### 5/5 — Cool app

*2026-02-28, version 3.6.6*

It works perfectly well but I have a question how to connect two 2.0 and one 3.0 in one profile because I don’t know how to do that

### 5/5 — Génial!

*2026-01-30, version 3.6.1*

Le seul défaut c’est qu’on ne peux pas programmer des degrés spécifiques pour faire des choses plus complexes.
Alors si possible ajoutez cela.

### 5/5 — Now the firmware update for Buwizz 2 works

*2025-11-07, version 3.5.4*

After failing with the firmware update, now it works

### 4/5 — It is kinda great

*2025-09-27, version 3.5.3*

I use the BuWizz 3.0 pro it’s great and all but I have trouble with steering control it would twitch a lot I wish they add the steering angle limiter like on Rc car steering when at wrong angles

### 2/5 — Connection is horrible

*2025-06-08, version 3.5.1*

Not sure what the hype was about but I purchased BuWizz 2.0 for my MOC and the battery has been horrible. Even with being directly next to the unit, the battery constantly disconnects and reconnects. This may be first and last BuWizz purchase

### 1/5 — Disappointing

*2025-05-06, version 3.5.1*

Center steering doesn’t work with the Audi E-tron and BuWizz 3.0

### 1/5 — Update 3.2.15 Breaks multiple BuWizz functionality

*2025-02-22, version 3.4.6*

Ever since the update listed in the title my 6x BuWizz 3.0 Pro car now has major issues and no longer drivable. There is major lag on inputs for each additional unit. With only 1 or 2 BuWizz 3.0 Pro it’s manageable but with 4+ the input lag becomes so egregious that the car will drive for 5-7 seconds after I’ve let off the throttle. Terrible update. With that being said the functionality and idea of the app are amazing but this update hurt a lot. 

Update: Original review was in August. It is now November. Still no fix.

Second update : End of December, still no fix.

Third update : End of January, still no fix.

Fourth update : 3.4.6 does not fix the issue on iOS or Android devices. I will not be spending any more time or money on this product. 

P.S. If you are using 3 or less BuWizz 3.0 Pro, you should have no issues, any more than that and there is a huge latency issue that has yet to be resolved.

### 2/5 — Not possibile to drive a model with version 3.4.6

*2025-02-22, version 3.4.6*

With version 3.4.6 i cannot connect to the BuWizz 3 pro hub on model driver mode. Checking firmware works OK, but when I choose to driver a model, three is Connecting green bar and nothing happens. GeForce lasy updated app was working. Hub 3 pro with fw 3.22 and 1.10

### 2/5 — Bad Update

*2025-02-15, version 3.4.6*

Addressing connection issues is a very good thing. Unfortunately this update forces me to to install a new firmware in every BuWizz 2.0 that I own which drastically changes the way the BuWizz works. It now doesn’t go into standby once you disconnect the phone, instead it stays on until you press the button again. 

A couple of my MOCs have the BuWizz buried so deeply that I turn it on by plugging it in (through a fixed extension chord in the model). With this new update, I now have no possibility to turn these ones off once they’re on. 

I just don’t understand why every update has these huge problems. Why would you fundamentally change the way of operation of a device that’s been available for more than 6 years?

### 1/5 — Disaster

*2025-02-11, version 3.4.6*

After firmware update my model cannot be driven like before; commands arrive late, there is a gap in time from action in the app and response from BuWizz. I use the BuWizz 2.0. I want to revert back…
