I've had this for several months. I won't repeat the criticisms that others have made about it (and with which I agree) but I'll mention something which I don't think others have picked up on.

I have had several bulbs "blow" in quick succession and so I wanted to check the voltage being delivered to my house. The reading was around 250 volts and, over several weeks, has stayed that way, sometimes reading as much as 253 volts and never less than 248 volts. 252 volts is at the limit of the permissible range before one can complain to the electricity company. So I thought I would check with a known-to-be-accurate multimeter. That read 230 volts - which is what it should be.

If the voltage reading is so badly out then just how accurate are the other readings? In other words, is it any use at all?
