I compared the Jool brand on Flip doorknob cover with a Walmart brand. I like that the Jool is more sleek, the Walmart one is more clunky. I bought an 80-piece safety set in Walmart with different safety locks. I think it was a better deal off the bat, because I bought in bulk, but if using the Flip perks I think it’s worth getting these covers from Flip if looking at the bigger picture.
