Not at all. Glad to be able to share some info. I had to buy a new one myself recently as the plastic cap which holds the batteries in, had sheared off.
The new model has been developed further! When you switch it on, the tip flashes red intermittently like a strobe light. When you place it near a live part (e.g. just put it beside the rocker on an ordinary domestic light switch, while in the on position) or more importantly a bare live wire, the tip (which is white usually) glows red continuously. It switches itself off after 5 minutes but gives a high pitched beep to let know when it does it!
I think it's the best thing since sliced bread. Very handy when you have to change a light bulb in a hall where there is 2 way switching - now you can be sure it's switched off when you go to take out the bulb.
