If it's free, then do it. Why wouldn't you? Even if you eventually get it detailed properly later on, it's free...and it's fairly decent
I got it free with the F10 and it's not bad, I've cleaned my car three times in 5 months, just a foam and shampoo job and the beading has been excellent throughout that time. I've no doubts it will wear off in a year, maybe less, but when that happens I'll just go back to using a decent wax and sealant. Inside it's been good to have with a toddler spilling stuff on floor mats, just comes right off.
