I like their simplicity, they don't use too many colors or graphics that you'd see in other similar services/websites out there (but not so simple).
They are very professional when it comes to website development as well UX / UI designs - easy customizable options for any project. Not much of anything really but if your looking at something simplistic with clean lines this might be what fits best! The concept can also help companies understand how users interact within an eCommerce platform while designing marketing campaigns through social media platforms such as Instagram & Facebook advertising etc..
