“Very good!!!!Love it!! And I love the guys supporting me kindly and quickly!!!”
“Avoid. Predatory billing and awful customer service. Charged two years in a row for an unused annual subscription with no renewal warning. Cancelling forces you to lose access immediately, which traps users into renewing again. Support was slow, evasive, and blamed Stripe instead”
