Great offer. Best parts

Worked on Mercury 2006 40hp 4-stroke Bigfoot. Appearance was the same as the original, seems well built. I order a spare part at this price. Great offer.

Pros
  • Handy item
Cons
  • Big and bulky

It works great and is easy to install

This is the second order for this product. We replaced one last fall and it worked great so we decided to replace the other 2 as well. Great price with fast shipping too.

Pros
  • Delivery was very quick
Cons
  • Small things

Simple solution and a hundred dollars less.

I've been using it almost every day since I bought it. It works great and I haven't had any problems since. OVER $100 CHEAPER THAN DEALER. Diagnosis was easy as I could determine which cylinder was failing by pulling out the spark plug wires one at a time. I then swapped out the spool for one of the two and the dead cylinder was now where I moved the spool to. Revain got it to me at least 2 days faster than the $163 retailer(s). All were the same price and it was sold out.

Pros
  • Handsfree
Cons
  • Functionality

I left the rest as spares, knowing that 1 suspicious original coil had already failed. However, the individual packaging of all 4 reels was badly damaged before being placed in the…

Pros
  • Easy to use
Cons
  • Some cons

A bad coil can burn your ECM

If I could rate ZERO stars I would except they at least require a signature for delivery. This is almost the only factor of salvation. Firstly, I don't even know if I received the right product because the devices are packaged in a single box with no part numbers and definitely no identification. Yes, they look identical to the original product, but that doesn't mean anything at all. Secondly, these coils are sold as non-genuine units, with the description saying "This ignition coil meets or…
