I recently switched from two-week contacts to dailies, and started using Hubble. What a great decision! I registered once, and now don't have to think about the logistics at all; a month supply of contacts shows up at my door a few days before I run out of my previous month supply.
For the most part, they fit well. There have been a few torn or dry lenses that I haven't been able to use, but I can't say if this is standard for daily contacts (the more containers you open, the more likely you are to have a faulty one). Also, I suspect you can get a more specifically tailored prescription through a traditional service.
Overall, I am very happy with Hubble! It's a great service that takes an annoyance out of my life.
Bottom Line: Yes, I would recommend this to a friend
