### 1/5 — USELESS

*2020-12-23, version 2.000*

I’d rate it lower if I could. Won’t pair with w studio. Scam

### 1/5 — Works 1% of the time

*2020-10-26, version 2.000*

You really need this app to work in order to control and adjust the devices. The app connects 1% of the time. So- I am researching investing in Sonos instead.

### 1/5 — Scam

*2020-04-19, version 2.000*

After spending a pretty penny on these speakers I have nothing but problems. Needed the speaker replaced. Issues with Static. Expensive speakers like these, I expect top of the line software. This app is trash. Does absolutely nothing and is never updated. Never will buy from this company again. Nothing but problems.

### 1/5 — Absolutely Useless

*2020-02-01, version 2.000*

The Most BS app after spending 1k on a product. Stay away from this product. There are better product with way better user interface

### 1/5 — Bad bad connection

*2020-01-21, version 2.000*

App and software on this brand is shameful. Over a thousand dollar price tag speakers, worse than cheap Chinese app. 
Why did they even bother launching it?

### 1/5 — Software platform is horrific

*2018-12-16, version 2.000*

Setup software is horrible. Error reporting of even worse. I've wasted so much time getting a simple wireless surround setup to work.

### 1/5 — I feel like I got scammed on the software

*2018-05-01, version 2.000*

I have no doubt that the speakers themselves are very good products. But, after spending $1000+ on the wireless surround sound speaker set up, I expect great software implementation and regular updates. But, unfortunately this is not the case, and needs major improvements for both the apps and speaker firmware, as well as regular updates; the apps haven’t been updated in a minimum of 3 months. Excellent hardware deserves excellent software, but this is not the case for Definitive. I feel like I got scammed on the software.

### 1/5 — Antiquated

*2018-01-26, version 2.000*

They need a modernized interface and need to work on usability. It’s like DOS in the 1980’s. Also, still no surround sound support for TV mode. I love Def Tech, but they need to address some serious gaps.

### 1/5 — What does this app do

*2018-01-20, version 2.000*

It’s pretty useless app, shows I have a connection with W Studio system and my W7 speakers, does nothing else, really sorry I spent all this money on speaker system that has no blue tooth, uses only WiFi and never stays connected! Yes I have a new router and modem purchased just for this system. Also no connectivity with Alexa, Siri. You need to work both apps for your equipment

### 1/5 — App broke

*2018-01-13, version 2.000*

App useless does not work!
