I bought 4 of these two weeks ago and had mixed results.
One had to be returned because it wouldn't take a picture. My other three are extremely picky on SD cards, some only work with PNY cards, others only worked with my Campbell Cameras SD cards.
The pictures are extremely washed out, even for a $25 camera the quality was spotty. Trigger speed and recovery time was closer to 10-15 seconds set at 5 second delay.
They're not the best but they're a good public land camera for a scrape or bed. I've personally had better luck with a Primos Bulletproof had off Amazon for $35 shipped.
