RadWish review for Upsell.com ‑ ReConvert Upsell

i came here after having many failed up sell attempts (from other apps). This is the most powerful i have found and will be keeping it for life long. the problem with other apps is that there is a very high risk of hurting conversion but this app never lets you face any such problems. the support is fantastic. they have feature request/ bug reports if you want anything more. overall the best app!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
