Lifespan of cheap speed sensors on Amazon

Ok so I called an automotive shop and they wanted a unheard of price to replace them. So then I called AutoZone for prices starting at $165.00 to $255.00 a piece. So I went on Amazon and found 4 for $43.43. Then my friend said that they wouldn't last long. But I had already ordered them, so we will see.

 

I hate to say it but your friends probably right

 

Odds are they will be bad/not work out of the box, been there done that with ATV electronics and seen plenty of it on vehicles that come into the shop.
Your better off paying more upfront for quality parts, cheap parts almost always cost more in the long run than buying a quality part to begin with.

 

Goin on 6 years with a cheapy Amazon replacement with zero issue on my truck.
