I purchased one.
I installed used batteries that only had 70% charge. The camera took 608 pics the first week and the battery level was down to 40%. Installed new batteries after the first week, I'll see what kind of service life I get on new batteries.
Super easy to setup, seems to have very good sensing and trigger times. pretty week IR night range.
All and all seems to be a very good inexpensive camera.
