The most common Trident AB complaint: bugs
Not impressed. Our first test had an issue and when we tried to make the changes necessary it just glitched and kept trying to load. So we created a new test, and it will not switch back and forth at all. Support tried to help, but doesn't seem to be able to figure out what is going on. We just want a refund and will try a different app instead.

Serious problems reviewers reported
Billing disputes, broken stores, misused data and missing features. Each one is a single merchant's account.
The app is faulty and causes rework - it removed all our variant images and caused lose of sales. Now we have hours of rework to just get our website back to where it was before implementing this app.
I ran one test on one product detail page. the goal was to test the product images. Test didn't work as it should. I immediately stopped it. But the app destroyed our product detail page. All images were a mess. Can't recommend it.
when I hopped on a call they promised free trial for 2 years, haven't received it since months. Also there's almost no live chat support, making it difficult to communicate. App does not show ATC performance as well, must be bug.
purtroppo non funziona. Dopo alcune ore non ha ancora generato impression nessuna delle due varianti. Ho aperto varie chat di assistenza in cui dicono di rispondere in 16 minuti ma dopo 24 ancora non hanno risposto. Intanto l'ABtest continua a non funzionare. Disinstallo tutto
The app not working, i just wanted to do an A/B test for shipping rate. The exchanges with support lasted four days. First, they asked me for an authentication code to access my store (which was strange), then they told me it was fixed but it still didn't work, and then they asked me to call them to fix it live, even though it had already been done normally. In conclusion, four days wasted for…
Very bad, I insist for a long time, has experienced constant error, delay, unable to create the test, can't choose the product after test finally launched the first product price, but it's very wonderful is a few hours later I products in the price of shopify concrete was somehow changed, changed to test the price of group B, ridiculous! Customer support is slow to respond, I can never reach…
