How do you know what your website looks like out in the wild? Sure you test with a half-dozen devices and browser types, but what about, say, the Yandex browser (big in Eastern Europe), or on a Chromebook, or on a Playstation, or even on a Blackberry? How much are these minority devices and browsers even used?

Echo Reflect (www.echoreflect.com) records every visit to your website, so you can see exactly who is finding you, and what they are doing when they find you on the web. It holds on to those recordings, so you can analyse your customer base, and the experience you provide them, in detail.
