I am a qualified electrician. I bought this to throw in the camper van in case some emergency fault finding is required. Small, compact and the carry bag is quite good. Just remember this isn't a $600 fluke.. it is a cheap $50 meter. So for the price I can't fault it. I wouldn't throw it around as it's build is not that ruggard, but with careful use and keeping it in it's storage bag, it should last the distance. Very happy.
