I started on the generic of Climara made by Mylan, and I have the same complaints everyone does - they were HUGE, didn't stick well, caused constant irritation, and were generally a (literal) pain in the ass. Plus, and this is relevant for someone who's worried about insurance, I had to fight constantly to get the insurance company to acknowledge that I was prescribed twice a week changes (the really stupid part is that they'd happily pay for the same dose at once a week, but doing that amount as half as much twice as often drove them up a wall and they took me with them on the trip!). Eventually I ended up having to fill the prescription as a box every two weeks instead, which = double the copay, of course. And if you use Express Scripts for your mail-order, which most people in the US seem to, forget about it; they would see my prescription for enough for 3 months at 2x weekly and cut it in half, without fail. My doctor called, my endo wrote letters, I called and argued every single time... no dice. The best I could do from them was also to get half a year's supply (with them insisting that that WAS a whole year, and that getting it refilled twice per month wouldn't mean my prescription for 12 months ran out faster, either), and after six months of trying I gave up and went back to the local pharmacy.
I switched to Vivelle and never looked back. Not only is it tiny and discreet and sticks well and is easy to use, it's packaged for twice a week - and lo and behold, like magic everyone stopped arguing about that part. Though now I'm tempted to try for the Canadian pharmacy route myself.
