Power Tools Suite

Update July 2023: We've been using the powertools filter app for about 5 years and are still very happy with it (we recently added the Powertool Suite which has given us increased functionality). The support is spectacular and willing to help troubleshoot, offer guidance, and even some customizations. Very affordable.
Original review: Excellent app. We spent considerable time trying to set up other product filter apps and none of them did what we needed. Power tools filter is incredibly customizable and there are tons of automatic installations meaning even those with little coding experience can implement these filters on their site. There are also helpful tutorials if you get stuck and support was excellent. I was initially hesitant at the price when compared to other filter apps but of the ones I looked at in depth Power Tools has many more features and is worth it.

PowerTools is a MUST HAVE for any Shop owner who enjoys making money more than wasting time! Get it now!

I don't know how we managed without this app before we had it. Saves 100 of hours in manual adjustments. Love that it auto hides out of stock items, and how you can make mass price changes for special offers. Very much worth the monthly fee.
