I have not installed this yet as the extreme temperatures are too high and I need to remove the bug repellent first. I ordered a set of screws based on the negative reviews for the glue. There is a little wiggle room to put screws in the right places but the quality of the product is very good. This can be worked out for several models, my 2008 is a little behind but still doable. Looks like I won't be able to keep the bug repellent due to the screw placement. If the installation is successful, it is a good upgrade for summer and winter. Will be updated after installation.
