The IR remote control is a very useful accessory. The function is fully consistent with the expectations. For the low price, there is no reason not to buy the original. Compared with other third-party remote control ML-L3 for me cut very well: compact, functional, inexpensive. In practice there are no complaints. The range is sufficient. When using with the D40x compared to the D90 D40x was even less complicated. The D90 responded in my experiments somewhat depending on the direction (which is of course more to the camera and is not related to the remote control). Ideal for tripod use for long exposures u. Ä.. In my camera bag it is in any case always.
