Product review (5 stars): Finally, a solution!
Had to invest in these since I got tired of little crumbs making their way to the bottom of the oven and filling my house with smoke. It seemed like I would spend forever cleaning it, then have to it again after someone cooked something, no matter what we did we just couldn't keep stuff from going down there. I was tired of opening the oven and having my eyes burn from all the smoke, not to mention how nasty it would make the house smell. It was embarrassing if we had guests over...but who has time to clean an oven over and over again? It takes FOREVER and no, the cleaning setting did not always do the trick.

I stumbled on these after skimming through one of Buzzfeed's many lists. I put them on my house wish list for a long time and after the 10th round of oven cleaning in 3 weeks said screw it and spent the money on them. I haven't had an issue since then! Should have bought these long before I did, but I don't regret it and so far have only had to use one liner! Happy camper!
