eufy Flex is not a financing (i.e. "buy-now-pay-later" by Affirm, Klarna, etc.) nor a rent-to-own program, so you don’t have to commit to a purchase spread out over a period of time until fully paid off.
Fragile does not offer rent-to-own or financing services. You may at any time ask that a policy exception request be filed on your behalf. This is the only case at which ownership is possible. Any exceptions are highly conditional to contextual circumstances.
