Mostly good goggles, discomfort on nose-bridge - not for big noses!
Color: Black (Black-color Lens)
It's difficult to find good quality goggles that I actually like, but these get pretty close. For context I swim every Monday before work as a workout, so there's a few aspects I look for/are important for me and these tick most of the boxes.
1) Comfort - Probably the most important factor. These are very comfortable around the eyes, the rubber is soft and they don't leave rings. My old goggles always did and walking into work with "raccoon eyes" turns heads. These don't leave rings and are still watertight. Only complaint is the plastic over the nose-bridge is angled inward, towards your nose, instead of outward away from your nose/following the line of your nose away from your face. And it's thick, so it digs into my nose. It's not a game-killer but I feel it and it's uncomfortable. It will be the thing that pushes me to try a different pair next time. If you have a "big" nose or one that curves outward from the top, I don't recommend these goggles. They will be uncomfortable for you.
2) Clarity - These are very clear and don't distort your vision underwater. They don't fog up (at least for now) and provide a wide range of vision. Good work.
3) Fitting - The strap is easy and intuitive to adjust but leaves a bit to be desired as it's a single strap around the back of your head. I like the security of 2 straps/a split strap that straddles the back of your head holding the goggles firm in place and preventing up/down movement. The good news is I haven't had issues with this yet, so it could just be a change in what I'm used to that makes no functional difference, but I'd be a little concerned to dive off a starting block as I'd worry they might release. Again, I HAVE NOT done this and I haven't had any issues, it is just a feeling. The button quick-release is a nice effortless way to pop them off when I finish and I'm tired!
4) Other - The case is a nice touch! I hate my goggles getting scratched and this helps prevent that. Nice to have.
Overall - They are comfortable around the eyes, don't leave rings, are clear & don't fog up, and functionally have been great with the quick-release & included case. They may be uncomfortable on "big" or "protruding" noses due to nose-bridge design & thickness.
4 stars because they dig into my nose a bit...and I never thought I had a funny nose but maybe I do!

Great customer support, but blurry underwater for me.
Color: Blue Hawaii
I'm a casual lap swimmer who swims 30 minutes every day. Needed some decent goggles and saw the Aegend brand was a highly rated bestseller. I first ordered the mirrored version of this lens which is essentially identical to this clear version. Was really excited to hit the pool when I received the goggles. Love the strap system on these Aegends which adjust on the back and has a quick release button...my other goggles have a little short strap that adjusts at the temple and it drives me crazy. Goggles are very comfortable and never fogged up during my swim. Nice field of view.
What's the issue then? These goggles are perfectly fine and clear above water, but blurry underwater. The blurriness is like a prism effect. My local YMCA has small tiles and with these goggles the tile lines were duplicated several times over. The effect isn't bad and perhaps some may be able to live with it, but it was annoying to me. Contacted Aegend customer service and they asked if I was myopic (no) and offered to send a replacement free of charge including a choice of couple different models. I chose instead to return the mirrored version and rebuy this clear one thinking perhaps the mirrored tint had something to do with it. Second pair of goggles arrived and same thing--clear above water and blurry underwater. Aegend says not everybody's eyeballs are built the same and again offered to replace the goggle free of charge including to their flat lens which shouldn't have the blurry prism effect. I declined since I know the strap design on their flat lens goggle would drive me crazy.
So in summary--these goggles are great and customer support is first rate. But I cannot give the goggles 5 stars since they didn't work for my eye profile and caused everything underwater to be blurry. Doesn't seem like the majority of people buying these goggles have the same issue though so I wouldn't hesitate buying them to see if they work for you.
UPDATE 2/14/17. I'm revising my review to 5-stars. Aegend once again contacted me and tried to make things right. They had another swim goggles with the clasp on the back like the one for this product but with a flat lens (https://www.amazon.com/dp/B01MTXI8SV). These new goggle work great and are clear underwater. Can't say enough about a company that stands by their products like Aegend.

Excellent Goggles — Comfortable, Secure, and No Leaks
Color: Aqua
These goggles are excellent quality and were very easy to adjust. They have good suction and fit nice and tight without being uncomfortable and stayed secure the entire time I was swimming. Not much for style, but these do look pretty cool.
I wore them for about an hour with no issues at all—they remained comfortable and didn’t leak, which is a huge plus. The seal held up well without leaving painful pressure marks.
The included case is also a great bonus and makes storage and travel easy. Overall, a very solid pair of goggles that perform exactly as expected. Definitely recommend.
