INCREDIBLE Support - Wow, I am blown away by the support I have received during the free trial, allowing me to fully launch in just a few hours and have all of my concerns responded to, even when they required some coding from the backend. Looks great on the front end and works like a charm! Thank you!

SERVERS CONSTANTLY DOWN - I also have to edit my review. Their servers are down constantly! It has been OVER 30 hours now, and they've still not responded to ANY of my messages or email! I pay them $900 a month. This is OUTRAGEOUS. RUN AWAY, as fast as you can!!! Original review, to show you what crappy serve technology can ruin: "Spectacular software, extremely well-polished, coupled with world-class support. Highly recommended!"

Amazing Support - Got the filtering set up (so far the functionality seems very good and exactly what we need) and ran across a few issues with display on the website, messaged them through the chat function and their development team had resolved all the issues within a few hours. Amazing!

Great App Ruined by Terrible Server Infrastructure - UPDATED to 1-STAR: We've been using this app for over a year now and it's still great, but their server infrastructure needs fixed and fallbacks in place. We've tolerated quite a few outages since those usually only last a few minutes to an hour and have gotten better over the last few months. Unfortunately, the entire app has been broken for over a day as I write this update and their response has been mediocre at best. They won't give me an ETA. I get things happen, but your service can't be down for days when it powers critical parts of a website (both category and site search in our case). Such a shame, but we're looking into alternatives.ORIGINAL 5-STAR REVIEW:I stumbled upon this app while researching a way to show filters across the top of category pages vs. the typical left sidebar approach. I'm very picky when it comes to making sure any app we use integrates perfectly into our store, meaning no weird UX issues, slow loading, etc., so I was a bit skeptical at first. The out of the box version is solid with tons of customization options via their app settings, and their documentation is good too (albeit referencing Shopify everywhere). Still, you may run into an issue or two or want something to work a bit differently. Thankfully, their support is one of the best I've experienced. I sent no less than 13 emails during our free trial period to make sure everything was exactly how we wanted it. Their team fixed all the bugs I found, customized a few things to our liking, and even added a few features to the app based on our requests (ability to set custom hex code for color swatches and ability to use a custom image as a swatch). I'm sure the app will only keep getting better with more features, such as other ones we requested, including the site search also indexing/showing pages, and the category pages using the set product sort ordering from BigCommerce product admin for how products are ordered on category pages. Definitely give this app a shot if you're looking for either a site search solution and/or a better way to filter and display your products on the category pages.

Good App - Great App with quick response from the customer care and they will solve the problem for sure. Nice!

Best Support - We needed a better search filter than the one that came with our template, and USF was the right choice. We had a custom installation done on our theme, and the support we received was first class. The first iteration of customization wasn't quite right - so we reached out to the USF team, and they were extremely responsive, professional, and efficient. They helped us to get the filters working exactly how we wanted them very quickly. I would highly recommend this product.

App for everyone - Excellent app. The team supported integration and helped through very step of the process and the app works perfectly

Good support - Experienced a minor issue with CSS and the team jumped in and helped in minutes. Stellar support!!

Amazing - This app and the entire team is absolutely amazing!!! Nancy has been the biggest help with everything possible and beyond (including page speed!). I am extremely lucky to have found such a great app that not only works but the customer service is incredible. I tried several other search apps before and didn't really see the value added. With ultimate search the feature that shows the product as variants, that's amazing.Highly highly recommended!

Fantasic App - Wow! This app is really going to change the game! Essentially, you get MANY apps in one. Here are a handful of the amazing features I’ve discovered thus far:- Fantastic, speedy support- Wide range of look & feel customization options- Integration options (biggest advantage for me is Judge.Me, but there are a ton more!)- Both collection AND search filters with the ability to create custom filters for different collections, if desired- ***HUGE benefit you likely won’t be able to find anywhere else: Filter by variant where image seamlessly switches with variant selection!***- Ability to create search synonyms- Merchandising/boosting/pinning specific products- Filter by tags, collections, product options and more — manually select the specific ones you want shown or have them automatically all shown- Quick view on search result products- Custom collection or search banners- Search analytics

Intuitive app - Intuitive and fast app. They have helped me set up a nice filter on my site. Good job team.It's also an extremely powerful app. Variant filtering powerhouse and dynamic custom field are unmatched by any app.

Doesn't work - Where to begin? I really wanted to like this app. It "looks" sleek. That is unfortunately where the positives end. This has been the worst experience I've ever had with any app ever. This never worked. Out of stock products only showed on some pages despite the settings being set otherwise, and the customer service was absolutely abysmal. It took several days to hear back about a critical error, and after deactivating the theme customer service reactivated it without telling me. Run far away from this app. We never made it past the trial period because it never worked. The best support we got was when we uninstalled the product and got an email instantly. It actually pained me to have to reinstall this app just to write this review.
