SWOLE O'clock® review for My Product Registration

I used this app to upload serial number of our product to our website. Our customer can register their product and validate the authentication of purchased product.Yeah, it's what i looking so far :). And, I have little problem when i want to delete bulk of serial numbers which uploaded wrong. The app do not support to do bulk deletion. So i asked from support team, they helped to do that (within 24 hrs ).Its great! Anyway, I think it could be great if they can develop this function too, to clean up our database or sometimes it's wrong uploaded.
