Negative Positive
Title: el-cheepo
Review: This is way to cheaply made I am disappointed (well not really typical chinese product ). My fault to buy it.The manual in the box is for a totally different item .... not surprised.I only needed this for very simple tests so tried keep the cost low (and I have a much higher end product somewhere in the moving boxes).For anything real DO NOT buy this ...OH YES require a 9V battery which is not mentioned and not included ....
Is the review positive or negative?
