Thanks. That will come in handy if I need to pick up another couple of pair. Have friends that might come over this weekend. There's 5 of them, and 4 of us, so we'd be two glasses short. And BB now no longer has these on sale.
I haven't watched a full movie with these myself (I used the Epsons (since they fit better on me) while the kids and guests used the PS glasses), but will have to see what I think of them long term. Initially saw no issues. Had no complaint from others using them though.
The one draw back is the rechargeable batteries (IMHO), and the SHORT USB recharging cables. That said, I had all 5 glasses charged in about 1 hour fully from only two USB chargers, so either they charge quickly, or out of the box they were pretty well charged. Need to get a 5+ port USB hub so that I can plug them all in at once, though the short cabled may make that a bit difficult.
