Hi all, I'm looking to purchase 2 tap to donate machines for a large corporate partnership I'm running. We'd like to trial having one in a podium in the office lobby, and one we can take to smaller events. Our main concerns are user friendly, strong connectivity/ability to take offline donations, and option to change donation amounts. 

So far I have spoken to Goodbox and Collectin. 

Does anyone have experience using either of their products and would you recommend?

Thanks in advance!
