Bests & Worsts Reviews from Amazon

Product is 5/5 but im a little bit concerned because the seal was broken and was replaced with a fake seal. after careful examination i have found out that original seal was underneath the fake one. I'm in the u.s. and i had to go on a Singaporean samsung website to register my product. shouldn't internationals versions be able to register from any where? so i do not know what to do if my product malfunctions. So buyer be aware.
