Up to six pairs of these devices will work with the LG 47LX9500. The price has changed a lot over time. Bought for about $80, then a few more for $23(!), now they've gone back up to $50. We normally use all six pairs at once and we haven't had a single complaint of their failure. I have a habit of recharging them after watching a movie so they never died during a movie. They turn off automatically when no 3D signal is available and fit comfortably. I wear glasses myself and they still fit well and cause no discomfort. The pleasant moment is that each pair comes with its own cleaning cloth in addition to the standard charging cable and instruction CD. I keep them boxed when not in use to keep them safe and healthy. (In a household with 5 children aged 2-14 this can be a problem!) The charging cable connector is discreet and has a cover which can make it difficult to connect the cable. Use them very often, it's just a minor annoyance. If you use them frequently, the lid may come off, or you may just learn to deal with it. be reliable and easy to use. There were no issues with crosstalk, timing issues, or other pitfalls that come with 3D display. We look at Blu-ray 3D via HTPC with PowerDVD 11.
