Is there a free or trial version available?.
Right now we don't have a free version of Synergy available and we don't currently offer a trial version for non-business customers. Remember, we have a 100% Seamless Guarantee, meaning we'll give you a full refund instantly if you're not happy in any way (so long as you let us know you want a refund within 30 days of purchase)
