Very good device! The display is accurate, there is a large screen, the measurement readings are clearly visible on the display. Large comfortable rubber buttons. The menu is simple and clear, there is no need to do anything extra. When purchasing, I doubted that there was very little information and video reviews on this device. It’s good that the doubts were in vain, good device. Delivered very quickly, six days ahead of schedule. Thank you very much!

I thought for a long time and chose to buy myself some normal, not entirely cheap battery tests and decided to take the risk of taking this one. (I already have a couple of inexpensive ones). Since there are practically no reviews about it, I took it to my own risk. Well, I think there can’t be anything bad for that kind of money, because this model is being made for the States. The long-awaited tester has arrived and… it does NOT work out of the box… It does not turn on when connected to the battery. How so… How do they test them before selling – the question. I’mshocked. I wrote to the seller… The seller answered me for a very long time in our correspondence. Then he convinced me to close the dispute, and only then will he return the money.
As a result, I did not close the dispute and he still returned the money 100%, but the sediment remained ((
Apparently, there are selection ones for the States, but for us there is a thinning rod (I think so). But, since the money was returned to me, I decided to order from this seller again, it’s not enough, I was lucky for the first time!) I want to find a normal device. Let’s see what comes out of this.
