I've never had one of these before, so it took some getting used to. The device itself is fine. I mainly picked this one for the tweezers, but they are too long to see well enough to use. My main gripe is the app that you have to use. It's not like any other app I've used. It's actually like its own wifi, so you have to disconnect data and other wifi to use it. It did connect and allow me to use the camera, but it messed up my phone horribly, and I've since uninstalled the app, so I can't use the device anymore either.
