### 1/5 — Device sharing doesn’t work

*2026-02-22*

When a company releases an app and they clearly have their worst developers working on it and the devices sharing doesn’t even work, you know you have hit rock bottom as a company.

### 1/5 — App is broken im 2fA

*2024-03-02*

App gets stuck in a two factor loop and you can’t sign up.

### 1/5 — Horrible Product!!

*2022-05-14*

If I could give this a negative rating I would … TOPENS will only allow you to connect to their own products. That means you have to have a separate clicker per car to operate the gate. You cannot link to other remotes. The app, I cannot connect either … I do not like the app or product… finally, during the attempt to connect the app - my remotes stopped working locking me in my backyard!! I’m getting my contractor to replace this entire product for one that is made in the EU or America!

### 1/5 — App is broken

*2022-02-01*

Unable to register or create an account due to graphical issues. The register and login buttons are white and won’t allow me to click them. I think it’s the login and register since I can’t see it. 

Please update :)
