Title is enough said. I got the AN-3dg10-s for free with the TV projects. Could not stop myself from getting the AN-3dg20-b once I was told the price of $85 less then what Sharp was recommending the price. 30 hours of usage between charges with an 90 minute charge time equals zero need for batteries. Light weight and simple looking compared to An-3dg10-s. Only need to switch postion on knob compared to holding button to turn on or off. So far so good.

I ordered 4 Sharp AN3DG20B 3D Glasses from amazon for my Sharp LC70LE735U and LOVE them. Lightweight and comfortable. I don't know what the more expensive ones feel like but these are Excellent. I would say don't waste the extra $75 on them just buy these. Plus if you scratch or break these lenses it's only $75 to replace rather than $150.

The only thing I wish I could do is have the option to replace the battery easier if I ran out of juice. But what the hay who watches more than 9 hours of 3D right? Well maybe my son playing the PS3.

I didn't have a 3D disc but my son had a Ratchet and Clank 3D PS3 game so we loaded the newest firmware on it which supports 3D and WOW WOW WOW. Insane to play this game in 3D. I can't play but my son is an expert (what 14 yr old isn't) and watching him play this game was like watching a movie in 3D. Things were just flying at us and it seemed like we could see behind the people and objects.
Can't wait to get Avatar 3D.

glasses came free w/60" sharp 3d tv i also bought at amazon! they work great, light and very cool looking! very easy to use, and charge up by pluging up to any usb port!
