5 stars for customer service! I'm on a free trial for both Monster Upsells and Monster Checkout at the moment. It's very easy to use and the checkout looks great without any coding. The customer service has been incredible so far with staff helping me through set up and offering advice.

Just started our free trial and it's fantastic so far - loving the features and the devs are really hands on and helpful. Seems to offer pretty much everything you'd want from an upsell, and the dash is very easy to navigate. Fingers crossed for a great result!

Best App! Was walked through the installation via support and they had it up and running within minutes. Just turned a $200 sale into $280 sale with the upsell. Definitely worth installing!

Buggy and never worked correctly. Chased their "support" for weeks, trying to get them to fix a problem with the app. Support lied to me multiple times, claiming it was fixed when it wasn't.
