Query: What happened to these?

I used to be a fan of these goggles and used them for several years with a level of satisfaction that would have earned them at least a four-star rating. However, after purchasing a new pair recently, I've had nothing but problems. No matter how I adjust the fit, I get incredible leaks after only 25m. It's a shame because I really do like the clarity of the lenses and how bright and crisp everything appears through them. Obviously, though, when you're not able to get an effective workout for having to empty your goggles every 100m (if you're lucky), nice lenses are hardly worth having. I won't be spending my money on another pair of these again.
