Design and material quality lead to frustration in use

Design and material quality lead to frustration in use
Here we havea great concept. A handy, easy to use, circuit tester without the complexity of a meter. For four months, I hardly touched my digital volt meter, just used these to maintain the four marine engines under my care. But...all are not created equal. On the left in the photo you see the black corded Winamoo Upgraded 3-72V Automotive Circuit Tester with Voltmeter, Heavy Duty LCD Backlight Display Test Light with 140 Inch Extended Wire & Illumination, Bidirectional DC Voltage Tester Electric Light Test Pen. On the right you see the red corded JASTIND Heavy Duty 3-48V Backlit Digital LCD Circuit Tester, Test Light with 140 Inch Extended cord. The Winamoo black unit's clamp is easy to use and well insulated. The Jastind red unit's clamp is cheap stiff plastic insulation always falling off and very hard to squeeze the clamp which does not open wide enough even for a threaded battery terminal. Then note the cheap repurposed screw driver handle on the red Jastind. The Winamoo is larger, sturdier and easier to position in your hand. As for the black vs. red cord, the black is flexible, thicker, obviously higher quality and much easier to use. The red Winamoo cord is cheap, stiff plastic. The black Winamoo has an integral tip guard. The Jastind has no integral guard to protect you from that sharp tip. The black Winamoo includes a very useful polarity light and task light. The Jastind does not offer these features. Neither unit is fused for current protection and there is no over voltage protection. Note the red logic module on our red cord Jastind failed on us and we surmise, since they sell replacemens on Amazon, that this is a frequent occurence. Note the Winamoo has a higher voltage rating which may make it more insensitive to failing with certain loads and it has not failed yet although we have only used it a few times to date. The Winamoo black cord product is useful in real world applications like ours where we are maintaining several ocean going fishing vessels. The red cord Jastind device is frustrating in use. Pay a dollar or two more and get the Winamoo!
