## Description

Product Description Comparing VT100 ST100 HT100S VT200

Review: A very functional device with some pleasant features. - These types of tools are invaluable around the house. I had one previous and that starting playing up so I went for this Kaiweets model. I think their goods are pretty decent for the price, and sit between the cheap and premium quality in general. After a few months, I can say the tool works quite well and provides a serious DIYer electrician a few more features than your basic NC Pen. Build quality seems pretty robust. The outer plastic is hard and solid and I feel it may take a drop or two but obviously don’t just throw it in a toolbox. Store it in its own box until needed. It’s a safety device after all. The sound and light alerts are absolutely clear and will get your attention, and others around you too. The sensitivity settings as well as the varying frequencies of the sounds and lights help provide more context to the nature of the current. The built-in light is an extremely thoughtful and useful design feature. With one button you can illuminate a dark space under the floorboard as you test for breaks in a wire. I love that it does auto shut off in 5 minutes as I’ve noticed I’ve forgotten to turn it off manually a few times. Batteries are included in the pack which means you can starting using the device immediately. Overall an excellent tool for a reasonable cost, with a very confident 36 month warranty so definitely worth an investment.
Review: No fuss voltage tester. - Absolutely anyone can use this, it is so simple and easy to use. Just turn it on and touch the end on the chosen area to be tested and it will beep faster the closer you get if there is voltage present. It is highly accurate and has been used many times since I bought it, especially on cables and sockets. The voltage tester is of good quality and is well put together, it also looks very good for the price. The size is small enough you can just put it in your pocket and not worry about it taking up to much space. If you are after a voltage tester that's easy to use and doesn't cost a fortune then you don't have to look any further, this is for you.
