Handy piece of kit
Batteries that arrived with this unit were flat which was a bit of a disappointment. I would strongly urge any electrical engineer to get one of these or an equivalent - I nearly had a BIG accident quite a few years ago because I didn't have one of these (and didn't use a known live - my colleague stopped me in time!!)

Needs an On/Off switch
Arrived with flat batteries. I suspect that I may have to take the batteries out if I'm not using on a daily basis.

Good product, good price.
The product is fine but the 4 batteries supplied with it were flat.

Cheaper than regular calibration costs for domestic use
Confirm DMM voltage measurement quickly
