Taco ratings
Sizzy has been praised for its efficient multi-device view, time-saving responsive testing, and user-friendly interface. While there are some minor performance issues and limited built-in features, these are just small bumps on the road. Considering the overwhelmingly positive feedback from customers, Sizzy is a solid choice for those in need of a responsive design testing tool. With an overall rating of 4.5 and a 60-day money-back guarantee, it's definitely worth giving it a try.

Abandoned
I was very satisfied with Sizzy until the deal expired. Now, the developer is no longer responding to questions, the product is not being updated, and bugs remain unresolved. The browser engine is quite outdated and doesn't support new CSS rules, like nesting, which makes it unusable for me as a web developer. The roadmap and changelog were last updated several months ago, and there has been silence since then. The annoying bug still exists, where the dev tools always refresh when switching between tabs. The developer is aware of it but no fix so far.
I bought the product in june and never ever got any update for the browser.
Very disappointed - do not buy if it ever comes back.

Another wrong purchase on AppSumo
Sizzy has encountered the same problem with many other sellers here on AppSumo lately. A few months after the end of sales (without the possibility of requesting a refund), the application is left to its own devices, with no further updates or support. AppSumo should find a way to curb these scammers.

The amount of time I save and the ease and speed to see the design errors in my websites are enough to give 5 tacos. Great value for a good price.

Must have for web devs
I know kitze from doing his course of ZeroToShipped. Great guy, always responds and great developer. He is very active on Twitter, if there is any issues, will respond quickly.
This app is great for web devs. I like most the view of different devices when coding, so we can quickly encounter bugs on the frontend. The tool seems to be updated often.
