The ease of use is great! You can pay in cash or via card with no problems at all - it's so simple that I didn't even know you could do this until after signing up (I'm not techy!). It was nice being able make payments without having my details out there online somewhere too; however they are now asking me if i want an app which isn’t available yet but will be soon as well? So we'll see how easy/hard using their own mobile version would actually work when released :) Definitely worth trying though- excellent service & price point compared other providers such has Worldpay etc., plus its free trial period makes paying nothing riskier than any others really!!
