As it is not well known name in this segment. Perhaps I bought the fluke. when I attempted to power it up there was just a black screen. nothing. when I open a mailing package . in which. it deliverd extremely hot. I would suggest it would be so great if the shipping company STORE electronics in the cooler parts of trunks or deliver in the cool of the day. This way customer would not have to be concern in the item sitting it in old shipping trucks for hours on end prior to reaching its destination. This product has one quality that stylish looks attract to it
