Simple easy to understand directions. Wires marked & long enough to install with out extending.

Appears to be good quality but deceiving. Since install I have been having non stop issues with leaning fuel conditions. Similar to other posts

The wire is decent, relay works as it should. It's definitely worth the money.

Pretty decent quality for price and wires are very long so you won't run into shortness issue. Been on my k swap for about 1 month and no issue so far

They claim this is water proof. The relay is potted and looks to be waterproof. THe harness is not. If this is going into a wet area you need to put a good layer of dielectric grease in the sockets and maybe even electrical tape the bottom where the wiring goes in and around where the relay plugs in. That will protect it from splash. It should not be submerged in water. This has the wide blades on the load carrying terminals and the relay is rated at 40 amps. The relay is not diode protected across 86-85 which is the coil terminals.Butt connectors and a fuse is supplied. They also have heat shrink in the pack. I would recommend soldering the wiring. when connecting this in and using good heat shrink to cover the soldered connections. If you are using this to drive something other than the fuel pump if you are driving close to maximum rated current make sure your total length wiring supports the current draw. If you are not sure do a litte googling and reading so you make a trouble free circuit. I liked that the relay has the mounting tab. These types of relays are meant to be mounted vertically with the wires facing down. You should not mount them sideways or lay them at an angle. This is because the contacts are vibration sensitive if you dont mount them vertically. Mounting them vertically they are least affected by heavier cyclic vibration. I have seen relays momentarily bounce engage when not intentionally powered on, if mounted incorrectly.
