I've ordered these things at least 3 times and each time I send comments but nothing changes. This time after I got them and started using a pair, first the case clip came off, then one of the nose pads came off and is god knows where. I'm sure the next thing will be the case insert coming unglued from the case. All of these things have happened time and time again. But having the clip come off and losing the pad happened in record time after three days of use.Ordered a set of three 2.50 glasses. I've ordered very similar glasses from other vendors (eBay, etc) in the past... all made in China, all with the same nose pads that fall off and get lost after a short time (I did just find out that Newbee sells the replacement pads: https://www.amazon.com/gp/product/B01M0D0I88). TIP: pull the pad off when new, and dip the metal part of the nose piece in a bit of "super glue", then push the pad back into place.Anyway, so I pretty much knew what I was buying. However, all three pairs from this vendor had severe distortion in the lenses except in the very center... something I had never experienced before and found very distracting when wearing them. Returning these to this vendor (even before applying my nose pad "fix").I now have 6 pairs. I bought 2 pairs in light blue a couple of years ago and really liked them. They are lightweight and the case prevents scratches. I like being able to see over them if I forget to take them off. I was always putting them down and having to search for a pair, so I bought 4 more pairs, 2 pairs in silver and 2 pairs in red. I love them! If you've had cataract surgery like I did and now need readers, these can't be beat.Extremly poor quality. Poor quality control check. Pads on glasses were share and rubbed my nose. Not sure why but I could not drop this off at an Amazon return location. I had to find a box to put them in and had to stand in line at the post office to return the item. Will never buy this product again.unfortunately All 3 glasses ended up cracking. Weird part of it is the cracks are all in the same spot on the left lens. They are vertical cracks, from frame to frame very close to my nose. I just assumed I did not take proper care and broke a pair when I put it down too hard. But than the 2nd and the 3rd ended up breaking in the exact same spot. Fortunately it does not appear to have affected my vision as far as I can tell, but...I love this brand. Durable and stylish.GOOD QUALITYOn all three pairs the nose piece on the soft side has a sharp snag on the end where it cuts into my skin. Other than that they are fine so far.
