Go with OEM. Pay to play. Fork out the extra cash and just pay for the real deal.
Yes, the glass is fragile. Ive barely had mine on for 6 months and I already have to replace one. And at $94/ea, they can get pricey. Ive tried the Lamin-X thing and unless I did it wrong, that wont work. The bulb burns the cover. Id either suggest a few layers of clear packing tape or.....IDK.
And granted, I use mine ALL THE TIME. And I take long road trips, so they're on quite often and I do a lot of highway traveling. If it were less or more in town, Im sure they'd fair a lot better and last a lot longer.
