Aris Product Options, Variants

This is a great app if you need to add lots of options to your products, and want them to look appealing. I have used them for colour swatches and charm options which show up really well.
Their customer service is superb too. I recently had a little glitch on my website with the app so I messaged their customer support and Anne from the Aris team responded immediately and within 1/2 an hour it was fixed by the development team.
I would highly recommend this app.
