I did not hesitate long to buy this lamp the price for Epson EH-TW3200 my. Two to three times cheaper than others (compatible as well), I expect of course to see if it holds at least 1700h of my original lamp. Meanwhile, the brightness is equal to that of Epson for 1 and a half months and she moved easily.
EDIT 26/06/2015. She now 580h of operation and 1 year and two months. Still no problem!
