Very good telescope that works wonders with a DLP projector ACER H9501BD. The only difference noted with the official 3D glasses Acer is that lenses Zodiac glasses are slightly darker. It's light but it is noticeable when moving from the Zodiac SainSonic ACER glasses. Nevertheless I prefer ZODIAC glasses, because the price is 45 euros cheaper and ZODIAC recharge via USB cable supplied, while the ACER must change the battery (a shame for glasses 75) So do not hesitate a second. The glasses are excellent SainSonic Zodiac. I have the 203 and the 904. Personally, I find them more comfortable SainSonic Zodiac 904, as arms of the glasses less supportive behind the ears that can be annoying after 1 to 2 hours of viewing. So 203 fine, but the 904 best.
