The insert is really good. There is a noticeable difference in terms of a reduction of drafts and cool air. The window also looks nice. The seal is a good color. The fit is pretty good. It went in with some trouble and required a fair bit of adjusting. I think the end result is snug if maybe slightly on the too large size.
When all is said and done, it feels like the amount I paid is on the high side. I think it is just on the edge of worth it for me.
