DashSkin review for One Click Upsell ‑ Zipify OCU

Can't recommend this app. Our customers were adding upsell items to cart, and finding during checkout that the PRIMARY item they were trying to buy wasn't in the cart anymore (the most expensive, crucial item!). People were checking out with JUST upsell items. We were able to reproduce this issue on our own repeatedly. Kind of a joke. Then we noticed one of the upsell items wasn't successfully adding. We reported this issue issue to them, and they come back almost 2 weeks later to say they "fixed this issue in firefox", when Firefox was the only browser that DID work. Overall I feel like we were a very low priority for them and I don't feel like they cared much to read our report of the issue carefully, or take it very seriously. For what they charge per month plus their commission, the service was totally unacceptable.
