The Pro version is offered at a very good price and you think with it you have access to the latest models. When you start using it though "magic" settings picks which model is used and the answers produced are poor. When you select newer models your usage is throttled. I bought the sub and literally after three chats (not complex) my usage was 47% of my daily allowance and 10% of my monthly. The pro version is just another way to sell you credits

⭐ 1/5 — Very disappointing experience! I regret purchasing Merlin Pro. Video generation costs 600–1,800 credits per video, while my plan only includes 2,000 credits per month. These limitations were not clear before purchasing. I barely used the service and requested a refund just one day after the 3-day deadline, but support refused without offering any flexibility. Poor value for money and disappointing customer service. I would not recommend Merlin Pro.

I bought advertised yearly subscription for £25 but then after using it less then 2 days it wanted me to pay again for extra credits. no way. I emailed to support as they claim they will reply within 24-48 hours, now is over that frame, and still nothing. Not liking it anymore.
