These Haikubox models look a little different, but work the same way and provide the same features when you have an active membership (subscription). Don't want to pay for an annual subscription for a few years? The Prepaid 5-year Membership model is for you. Want to pay-as-you-go for full functionality or looking for a free but basic plan? Choose either the Basic (with 3-week trial) or Annual Membership (1-year membership included - what a great gift!) model. For a detailed comparison, see this document.
