To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This inexpensive and very portable test set can handle all manner of diodes and transistors, detecting type and pinouts on a colour screen. It can also accurately measure resistors and capacitors and reports ESR. The items can be inserted anywhere in the ZIF socket provided. It would have earned a fifth star if the ZIF socket could be mounted in a more stable fashion, but this is overcome with careful handling. Highly recommended - a very useful item for identifying and measuring all the usual single components.
I received this in good time and order. So far it has worked flawlessly for me. The accuracy is not that of a much more costly unit but this workes well for the price.i have recommended this to others.. It is good for a at home do it yourself type individual. But would lack in a every day hard use situation.
