The multimeter appears to be a very well made tool to add to my ever growing tool collection. It arrives with batteries to get you going right out of the box. You only need a regular Phillips head screwdriver to access the battery compartment. It appears as though you might need a mini Phillips but you only need a regular one. Also of note, the screw stays connected on the panel and does not fall out as you are putting in the three (provided) AA batteries. The unit has a very nice weight and hand to it. The plastic is very smooth finish wise and appears quite durable. I love that it comes in its own little black zippered pouch. This will assist me further with tool organization. Inside the pouch there is a pocket on the left for the multimeter. In the spine of the pouch, there are two elastic straps to keep the leads and probe secure and not tangled. Speaking of the leads, the black goes in COM and the red in VHz. You will need to remove the little cap at the end before inserting the lead into its appropriate receptacle. As the knob turns, it has an audible click and single beep to let you know you are in the correct position. When depressing the black trigger to open and close the jaws, it requires a substantial amount of force to ensure a snug fit when the jaws are clamped. I highly encourage you to read the manual for proper use. As well as peruse the website for further details and other VEVOR tools and accessories. The website states \"Tough tools half price\". There is a 30 money back guarantee as well as 12 month warranty. I will happily keep VEVOR on my radar in the future as I am genuinely impressed with this tool!
