The product looks good but by measuring the resistance is much higher than stated, ranging from 0,33 to 0,38.Anyway if not be important that difference the product looks good.Excellent shipment, really super fast. I purchased other resistance tolerance has been accurate to the millisecond.Maybe the error will be only for this lot, for this 4 stars.
