Review on RIVBOS RB831: The Ultimate Polarized Sports Sunglasses For Men With Unbreakable TR90 Frame by Michael Hicks

I've purchased 4 of these now, mostly lightning deals so I'm somewhere between $65-$80 invested. I've also purchased 3 of the kids version for my kids. My first pair I got back in 2018 so I've had these for a couple of years now.Pros:-Extremely cheap. As they break down I just buy new ones. Overall I've spent less on multiple pairs than I would have for a top name brand of equivalent quality. My old Oakley's are on par with these and my WileyX are slightly better.-Snug to the head without squeezing it. You can run for miles with these but they aren't tight enough to do a CrossFit workout or anything with vertical movements (burpees, box jumps, etc.). Initially they're alright but as you start to sweat they slip right off.-Polarized. Everyone should wear polarized sunglasses, especially when driving. Protect your eyes. If you need to see a screen then take them off momentarily. Also you don't need a screen when you're driving. Get off your phone.-Size is great for an average sized head. There no extension on the arms of the sunglasses but they're malleable enough that the bridge of the glasses will slightly bend to accommodate a larger head.Cons:-The lenses are not scratch resistant. If you put these in your pocket then they will eventually start scratching. It's best if you leave one in your car for driving.-Out of my four, three had the rubber pieces on the arms of the glasses come off. I had to reglue them back on with mixed results. Over time the adhesive fails and they come off.-The plastic at the join of the arms and frame is pretty low budget. Over time (4 months or so) it starts to get really loose and they will start to slip on your head much easier. You can retighten them pretty easily, I do, but after doing that 2-3 times the plastic itself starts to wear down where the screw is and it won't stay right.-If a lens pops out it's difficult to get back in. It was machined for the lenses to not come out in the first place so if they do it will be difficult to replace them.-Not malleable. If someone accidentally steps on then they'll pop out a lens and the arms may break. See the above two points.Tried to hit the highlights. It's legit just a cheap average pair of sunglasses with some nice Pros. I'm literally about to order my 5th pair right now because I like to wear them when I work out in the summer and my current one is getting looser. I keep a spare in my car, one in my beach bag now, one in the pocket of my uniform that I don't mind getting scratched up, and I have an extra one that's basically for parts in because one of the arms is broken (thanks kids)
