I needed a wireless remote so that I could tripod mount my D3200 and take closeup hummingbird pictures without spooking them. I found that Best Buy had the Nikon ML-L3 Wireless Remote at my closest store location and confirmed. When I arrived, there were none in stock. The rep suggested the Insignia remote which turned out to have a useful range listed as almost twice the Nikon. I decided it was cheap enough to try, so I bought it and used it immediately for the birds. Fantastic. My only issue is that it doesn't provide for activating remote video. No big deal, but it would be great. I also used it to eliminate camera shake the next night shooting the Perseid meteor shower. Again, great. I like it so much that I have attached it by lanyard directly to the camera strap so that I always have it available. I would say that this remote may not be essential, but when the need arises, for under $20, its a fabulous tool to have already added to your kit.
