Only Fans
I couldn't resist. . . .These little 12v Fans have been great. Bought for the back of my Jetta Sportwagen so the Kids would get more Air. 3+ Years on they're still working great. They're adjustable, have multiple mounting options, and have a variable speed control.
Silicone License Plate Frame
I only discovered these a couple years ago, but hands down best License Plate Frame you can get. I've got these on all the cars now. Eliminates all license plate rattles and looks great, especially with all the bolts capped off. How did I go so long without knowing about these?!
Gorilla Double Sided Mounting Tape
Accessories seems like the most appropriate category for this since it's a great way to attach many of them. This stuff is simply fantastic! It's been holding my 3d Printed Trim on the S10 Blazer for over 4 years now!!
Best Car Charger I've Ever Had
This is another one I bought for my excursion back from Cincinnati to Tampa when I bought the Suburban. I've been very impressed, it charges better than any other car charger we have, and that's been the case across about a dozen different devices. The extra USB port is a great feature as well.
