FORCEFLEX FF500 Heat | Flexible, Unbreakable Sports and Running Sunglasses for Men and Women

He loves it, he said. It stays put, and doesn't fall off.

I've never spent more than $5-10 for a pair of sunglasses before so this was kind of a major upgrade for me and I'm so happy I did. All my old sunglasses would fail in a myriad of ways: lenses popping out, screws unscrewing themselves and falling out, plastic breaking around the lenses, etc.This kind of manufactured product feels completely different. Bendable plastic while keeping a great hold on the lenses somehow!? I've contorted it on purpose a little bit and never heard anything creak or snap like an old pair of cheap glasses would have.There are some really nice touches to this item like semi-squishy pads for the bridge of my nose and possibly a few more places (describing from memory) such that I can wear them on hot days for extended periods and they do as much as they can to be unobtrusive and as comfortable as possible.As an avid hobby cyclist, I depend on my glasses to fit well, seal up my vision fairly close, and to come on/off easily sometimes with a bit of torque if I want to do it just with one hand. I've never been particularly gentle with this product and it is still performing just as well now as it did when it arrived new.Thanks for the great product! I'm really hoping you can stay in business without me needing to repurchase this every 2-3 years! It feels like a product that may last as long as 10+!

Loved the flexibility & comfort. A couple weeks in I slipped the glasses that were perched on the brim of my hat to put them on and noticed the right side seemed limp. As the picture shows a couple days later the piece fell off. As stated in the warranty, I sent an email with the invoice and picture so they could honor the lifetime warranty. It’s been over a week and have had no acknowledgment in any form. Hence the low rating

They look great and they are comfy also

I was tired of sunglasses breaking after about a year from normal use. These seemed tough and came with a guarantee. I was willing to spend more money to get sunglasses that would last, even though they looked kind of clunky.Unfortunately, they did break after about 18 months. I submitted a warranty claim through their website, and they initially said they would replace my glasses. But I've sent several follow up emails and over a month has passed, and no one responds. Buyer beware!
