Little update on the EVGlass from EVInsulate

So I went ahead and purchased the EVGlass for my 2020 M3 despite only finding a few YouTube videos from people talking about it. It's made in Ontario, so shipping to me as an Ontarian was fast and cheap (rare win for us here, lol). It's basically just a poly sheet with some fancy clear two-sided tape/gel around the perimeter. Install was very easy and I even fucked up the back panel by forgetting to remove the protective covering AND my peel strip on the two sided tape ripped. I had my 11 year old son help hold the panel up. I did install the optional 2-sided gray foam tape around the perimeter to help close the gap between the poly and the headliner. I am less concerned with factory aesthetics and more concerned with temp/efficiency. Even so, it's barely noticeable. While it hasn't yet been -19°C again, it has been -17 and the difference in the cabin is immediately noticeable. My eldest son noticed right away when I picked him up that his head wasn't cold and looked up and asked me questions about it. Will it increase the range? Meh, I suppose it may make a difference long term. Enough to really notice? Probably not. It is, however, much much more comfortable in the lower temps inside. Doing it for comfort alone is worth it. On that note, is it worth $270CAD? Eh... If it was $150-200 it'd be excellent value. At nearing $300, it's a bit much. I would, however, do it again. Worth it, but not perfect on the value front. That's pretty much my only complaint.
