This is great as it's relatively easy to set up and portable if you need to move. I was frustrated that I couldn't screw the bell button on initially, so I made a slight modification by carefully drilling holes in the base of the bell button. I of course had to remove the small circuit board which wasn't difficult, then screw everything in, then replace the circuit board and now it's attached to the door jamb! It's about as good as it gets for the price and I use it in case I'm upstairs and don't hear a knock. Very happy with the purchase.
