I had this app checked by our web developer before installing, he said it was very well made and is packed with features.

It has improved the speed of our website, and the search now worked perfectly.

Support is always at hand to help when required.

The power to filter specific variations was what we needed, and this app does it perfectly.

Give this a try before others,
