This is amazing. I used to install large 6" metal can lights (which is annoying) and it was a breeze by comparison. You can install them almost right on the stud, which is amazing. (I didn't do this, but they're definitely thin enough to do that if you position the clips in the right direction). Super bright. I have a 455 square foot garage and have installed 11 of these and they are insanely bright. Really very very happy with them. The 4 inch models here also have some really great wire pins making them a solid fit. (My buddy installed 6" and they didn't have spade lugs but they were fine. I just have to use spade nuts)
