It is not really regretting. I love both actually but thinking that I should just get either one. I like the mini vintage round first (I prefer the full silver one, but the shop only has the one with the rose gold in the middle new in stock, while the full silver one is the display item and looks quite used). But at the end I decided the mini silver heart - my dh also prefer the heart than the round, he thinks the round is flat and a little bit too thick. I think the vintage round is different and not as common as the heart one, while the heart lock gives sweet look, both are cute though. Btw if you want to get the vintage round lock, I think they are hard to find now, so you should get it soon if you like it.
