hereMy experience with OWC has been mixed so far.
I ordered my SSD around the time that Lion came out. Since I had to open the MacBook I also upgraded the RAM from 4 to 8GB and did a fresh install of Lion. So in fact I changed 3 things (the SSD, the RAM and the OS). Me bad, because since then I've suffered from beach ball effects

I suspected the wireless, but when firmware upgrade for the SSD was released I was eager to try it out.
My SSD is the "Extreme Pro 6G", and I have an early 2011 MacBook Pro, the only MacBook with SATA 6G ports, and therefore the only MacBook where it makes sense to install this SSD. It is also about the only MacBook
NOT supported by their firmware updater

(I don't have bootcamp / Windows).
In the end I took the SSD to a Windows PC, and upgraded the firmware. This, of course was what I had wanted to avoid when I shelled out what is essentially a Vertex3 with Mac support. I was surprised to see the PC (and the OWC utility) detect it as an "Electra 6G" (the entry level model). There's even an 'Electra' sticker on the front, even though the sticker on the back says 'Mercury Pro 6G". But the serial# on the back didn't match what the firmware utility showed.
Hmmm
It will be RMA-ed tomorrow.
