I received a clear and easy-to-follow video that explained where I went wrong with the setup and the extra features I was missing. Sometimes, we are so busy uploading these apps, and the good ones with great customer service stand out from the rest! I'm looking forward to seeing the AOV rise thanks to such a great app! Brilliant.

I am extremely pleased with the level of service I have received. There were two specific issues – one related to font color and the other regarding how the cart functioned within my theme. The customer service team has been exceptional, promptly addressing and correcting these issues. Normally, I do not leave reviews; however, their outstanding support has compelled me to share my positive experience with others. It is important to acknowledge when a company exceeds expectations, and I hope they continue to maintain this high standard of service.
