Review on Premium Magnetic Oil Drain Plug M18 x 1.5 Black Mishimoto - Boost Engine Protection by Allen Hart

I have used various Mishimoto products for many years and have found them to be excellent. This is a major disappointment in three areas: 1. Arrived broken in immaculate packaging. The magnet cracked. You might not even notice it unless you give it a slight tug when inspecting prior to installation. I assume the shock will be and the magnet will crack. Not suitable for vibration motors. Made in China, see pic 2. I have tried hand threading it into the oil pan of my 2014 Volvo XC90 but it seems to me that the large thread diameter is slightly larger. I ordered a Votex connector - DP007 stainless steel with neodymium magnet (M18-1.5) - MADE IN USA and it fits perfectly. I measure the Mishimoto's main diameter as 17.940mm, which is within the ANSI specification of 17.968-17.732mm, although on the large end of the spectrum.3. If a product has any of the above issues it can usually be assumed that it is a manufacturing defect as they do appear from time to time. That's where the guarantee should come from. Check the fine print on the LIFETIME Guarantee on their website. If you make a warranty claim for this small accessory within 90 days, you will be charged a $10 shipping fee. After 90 days. 15 dollars. Two years in your LIFETIME guarantee. 40€ shipping! For $15? INDEED?
