This is overall great app for automotive stores, probably the best ive tested. It works very well and the fitment function is easy to use. Individually, each car insertion is simple to use but I deal with mainly bulk import and this was the only year/make/model app that allowed me to easily apply large amounts of skus by excel. I gave it a 4 star as there were some little things I found annoying, like not being able to edit in bulk. Each edit per box has to be saved instead of revising every box on the page and then submitting. Also wish I could set the casing in the dropdown search as I have some all upper case make/models versus some that are all lower; this I could not revise no matter how I changed it. Would also like to see fitments not show up in drop down there were no linking skus. If these little annoyances were fixed I would definitely rate this a 5-star app.
