Отзыв о TWTADE TWTADE 4 Цифровой тахометр RPM Зеленый светодиод с проволочным магнитом Холл NPN Держатель датчика приближения ZSB5JT G от Totoy Wallsmith

Based on our own experience, this product failed to provide accurate readings and was not user-friendly at all .The green LED display was bright but the data it displayed was often incorrect. The wire magnet hall NPN proximity switch sensor holder was also flimsy and easily broke. The cons greatly outweighed the pros, making this INDUSTRIAL and scientific product a disappointment..
