In itself a great device. It detects which string is struck, for example, on the guitar or ukulele and displays using LCD hand, if the sound is too low or too high. Once you hit the clay, the backlight will turn green. Toll implemented and extremely helpful! Unfortunately, my unit came with faulty on / off switch. (You get what you pay for ...) Only about every tenth time pressures lead to a reaction. This is annoying, because you have to press a few seconds to turn on or to issue the product. If you have not caught the contact point of the switch because of the defect, you realize that, consequently, only after a few seconds. Then one presses again and again and again and so on ...
Not in my product review I will integrate the delivery time. She was in my case 5 weeks. Here you should look in advance where the goods will be sent! In my case it was a trader with US address, but returned from Singapore.
