After reading the reviews, I thought that either a) people who were writing the bad reviews were not regular swimmers and didn't know how to or were not used to wearing goggles or b) Speedo made a bad product.

For three years, I swam laps regularly - approximately 100 laps/day. However, when I went to grad school, I stopped swimming and gained a lot of weight (I was poor and had to eat cheap (i.e. bad) food.) So, I am an overweight plus-sized woman now, with a big head to boot. Now that I am starting to swim again (and lose those excess pounds), I needed a pair of good goggles. Despite my big head, I always loved Speedo products and needing prescription goggles, decided to go ahead and give this a try, hoping that Speedo would not go wrong.

I was not disappointed. When I received these goggles, I immediately extended the strap. Putting the goggles over my eyes, I could not see WHAT these people (the low reviewers) were talking about. If anything, I need to change the nose clip for one of the smaller clips that comes with the product. (This is my only complaint - it is not that easy for me to get the nose clip off - but then who wants it popping out while swimming??)

I figure that the low reviewers are not used to wearing good fitting goggles and are perhaps only recreational swimmers. These goggles form a GREAT seal - important for lap swimming - and are not too tight. They also are "not too small" or "for a child's head." In fact, I doubt they wouldn't fit on a child's head - they would require some serious adjustment. The cups fit perfectly on the eyes. By the way, non-serious swimmers, these are COMPETITION goggles and competition (serious) goggles are not supposed to fit like masks which fit over your whole orbital area up to your eyebrows. These fit very well over the eye as they are supposed to.

I did test my theory out - putting the goggles on my non-serious, very recreational, beach swimming roommate. Her immediate reaction was "These are uncomfortable."

While, I - a long time lap swimmer (minus my grad school, getting fat hiatus) - think these are awesome goggles. They fit wonderfully, give me a great seal, the prescription was amazingly good (as in, I can actually see - I bought 2.5 diopter), and the goggles are of high quality. I really like the straps. All this, and they were inexpensive!

My recommendations are as follows:

If you are not a serious swimmer, please do not buy goggles listed as "Competition" goggles. This usually means that the goggles are for serious swimmers who have different goggle needs and wants.

If you are a serious swimmer or on a swim team or actually in some sort of competition (or just know how to wear goggles), and need a prescription to boot - these goggles are EXCELLENT.

Now, let's just hope they last. 5 stars

Poor product , skimpped on the strap which is way too short , will fit a child's head .

Even with all that the extereme pressure on eye sockets , were leaking .

Prism doesn't allow to sneak peaks , goggles in general dont feel "right" .

I had many goggles beofre and have always adjusted but not to this one , gone back to my old Speedos .

Strongly advice to try before buying those goggles . 1 star

Overall I'm pleased with these goggles. I've wanted to get prescription swim goggles for a while, but assumed they'd be as expensive as prescription glasses. Apparently not the case.

My only complaint is that the strap doesn't loosen up enough. I have a somewhat large head (size 7-1/4), and at the loosest setting, these goggles are still a little tighter than I'd like. Hopefully the silicone strap will relax a little over time. 4 stars

My head is not big but still it was tight after fully extending and Eye cups are a little small too. Otherwise look a good value and of quality. comes in nice box. Just received, have not actually used yet. [...] 3 stars

It's good looking. Great price for OPTICAL AND RACER. Quite water tight ans slim. Only bad thing is the "smoke" is also not dark enough to swim under Texas sun. 4 stars
