I ride exclusively in ES pads. The quality is top notch. I order directly from ES, they’re really easy to work with and the prices are usually about the same or sometimes a little less than buying from a US vendor. You also get free shipping if you spend over 100 euros.
I will say I wash them by themselves, like one pad per load. If you put more in, they don’t come as clean.
ES has a lot of sales, especially now that Christmas is coming up. Also when they release new colors, they go live at 10am Stockholm time which I believe is 5am EST, in case you want to grab a new release and not worry about it selling out.
