I’ve been dealing with a serious issue caused by this app for over 8 days, and the experience has been extremely frustrating.

The app conflicts with other major third-party apps (like Hulk Product Options), causing duplicate cart items and double pricing. This is not a small issue it directly affects live stores, customers, and revenue. I lost potential clients because of this bug.

After thorough technical investigation, I confirmed that the app triggers an additional add.js call, which results in blank duplicate items being added to the cart. When I remove the W3 Product Accessories script, the issue is immediately resolved which clearly shows where the conflict originates.

Instead of working toward a real solution, support kept redirecting responsibility to the other app developer. While incompatibilities can happen, the lack of accountability and urgency was disappointing.

For a paid production store app, better compatibility handling and faster resolution should be expected.

Unfortunately, I cannot recommend this app if you are using other product customization apps.

Thank you for sharing your experience. We completely understand how stressful cart issues can be, especially when they impact live customers and revenue.

For clarity, we first received your support request on February 16 and began responding the same day. While that’s a shorter timeframe than mentioned, we know that even a couple of days with a cart issue can feel much longer when your store is affected.

When multiple apps modify the add-to-cart process, conflicts can sometimes occur. In those cases, duplicate or blank items can appear. It’s rarely intentional behavior from either app, but rather how the scripts interact within a specific theme setup.

That said, our goal is always to work toward a solution. We’re happy to review logs, adjust how our script attaches to the cart flow, or coordinate directly with another developer to implement a compatibility fix.

We genuinely want our app to work smoothly alongside others, and we’re always open to collaborating to make that happen. If you’re willing, we’d welcome the chance to continue working together and resolve this properly.

Very intuitive & easy to set up the accessories. Support is very helpful & the couple of small issues I've had over the years have been resolved quickly without hassle.

Had some hiccups with installing this on the Warehouse theme and using with Firefox. However customer service was super quick and friendly. We worked it out and everything looks great!

This app is terrific and gave us so much flexibility for displaying certain accessories. We had a few bugs when setting it up and W3 were absolutely brilliant in helping us iron out all the issues. Absolutely brilliant app and better customer service!

Product Accessories was just what we were looking for! This app is ideal for ecommerce stores looking to sell a few extra products while a customer is making a purchase. Very convenient for our customers to add pads to a product purchase or vice-versa

The best app I've ever used. And the app features are helping to increase my sales, as well as the tech support, which is amazing too! Whenever I have a problem and ask for assistance, the team solves it quickly. I like it, and great job!

The app looks great on my store! love the functionality and have made a few sales with it already paying for itself. Jason was very helpful with support and went the extra mile. Will use this app as long as I have the store thanks! Jake

This app is great and so is the support. We just started using it but it does exactly what we need. We needed some help fixing an issue and it was taken care of right away and no extra charge. I would highly recommend this app.
