Literally a no-hassle app. Once installed, it takes care of everything itself. The UI of the app is also suh-weeet!

So this is our second store that we have installed on. We installed on our first store last week and the results were excellent. We saved about 27% on average from the image sizes with no loss of quality. Install was easy and the app got working straight away at reducing image sizes. This is really a no brainer app for anyone wanting to improve their SEO. Highly recommended.
