I have been using Unicover for over 15 years with no problems. They are cheaper than Leer and have held up extremely well. I have taken 2 back windows out, backing unto the garage with the topper open, replaced the doors and kept right on going. They also fit correctly and I have never had leaking issues. The left is my 2008 Dodge, the right the 2012, both with the Unicover which I would highly recommend...
