Puffin Cloud Browser is a mobile browser that offers fast loading speeds and cloud protection. It is free to download from the Google Play Store, but a paid subscription is required for unlimited use. Users can try out the service for free with a one-hour daily usage limit during the evaluation period. The browser uses a proprietary compression algorithm to save up to 90% of bandwidth on regular web browsing. However, streaming Flash content or videos requires more bandwidth than normal usage.

The browser offers features such as an ad blocker, mobile, and desktop modes, download to cloud capabilities, theater mode for Flash videos and games, virtual trackpad and gamepad, and Adobe Flash support. The monthly subscription fee is $1 per month.

There are limitations to the service, such as geolocation restrictions of content if users are based in countries other than the US and Singapore, where Puffin's servers are located. Puffin is also blocked in certain regions, such as China, Saudi Arabia, and the United Arab Emirates, and some educational institutions in the US.

Overall, Puffin Cloud Browser is a fast and secure mobile browser that offers unique features such as cloud protection and Adobe Flash support.
