Thinking of canceling residential max plan

So I’ve had starlink for about 3weeks and I like the service but it’s not as great as I thought it would be. I requested the free mini that comes with it and I’ve been waiting almost a month for them to ship it 😬. The mini is the main reason why I even signed up for starlink.

I’m honestly thinking about canceling the plan and buying one from home depot and just doing it that way instead of the renting/leasing way. I’m curious if anyone has done this and had issues with canceling or swapping service plans?
